Survivor Philippines: Celebrity Doubles Showdown is the fourth and final season of the Philippine version of the reality television series Survivor.

Richard Gutierrez reprised his hosting stint for the second time after Survivor Philippines: Celebrity Showdown. This installment would feature celebrities contestants grouped as couples with preexisting relationships. Teasers of castaways' identities were partially revealed in the third week of October 2011. A week after the teasers were revealed, the identities of the celebrity castaways were then fully identified.

The show was entirely shot in San Vicente, Palawan, the first time the Philippine franchise has filmed in their home country. The show premiered on GMA Network on November 14, 2011.

Initial tribe names were Bulan ("moon" in Cuyonon and Visayan languages) and Tala (archaic Tagalog term for "star"), termed in-show to be names of goddesses of the moon and stars respectively. In the eventual merge, the new tribe was named Apolaki, after the Tagalog god of the sun and also the god of the warriors. Though the game is a doubles format, it was revealed in the first episode that only one will remain as the Celebrity Sole Survivor who will win ₱3,000,000.

This season is noted to be the one with the most number of quitters, as five separate contestants left the game voluntary during the first six days of the game due to mostly moral reasons. It also has a gender imbalance because there were nine males and eleven females.

The season was won by Albert "Betong" Sumaya Jr. with the vote of 4–2–1, defeating Mara Yokohama and Stef Prescott.

Twists and changes Aside from its biggest twist, which is the "doubles" concept, this season also featured old and new twists and changes into the game.

Temptation Reward: The winning tribe in a Reward Challenge would choose one or two of their own to partake in the Temptation Reward. After being shown the reward, the chosen one/s were then also presented with the consequence that comes upon accepting the Temptation Reward. Declining from the Temptation Reward is also an option, if those chosen would deem accepting it be too harmful for their life in the game. Tribal Shuffle: Occurring on Cycle 4, this ended the "doubles" format, as the pairs were broken down, with one going to Bulan and the other to Tala. Second Reward Challenge in a Cycle: Also used in season 2, this occurred on Cycle 11 when the castaways fought for a car.

The Total Votes is the number of votes a castaway has received during Tribal Councils (either solo or as part of a pair) where the castaway is eligible to be voted out of the game. It does not include the votes received during the final Tribal Council.

The game Cycles in this article refer to the three-day periods in the game (unless indicated), composed of at least the Immunity Challenge and the subsequent Tribal Council. Except on the first cycle, every cycle begins at the end of the previous Tribal Council. So any events that occurred after a Tribal Council will be chronicled in the next cycle.

In the case of multiple tribes or people who win reward or immunity, they are listed in order of finish, or alphabetically where it was a team effort; where one player won and invited others, the invitees are in brackets.

Episodes Cycle 1: Days 1-4 Pair Reward Challenge: Castaways must free themselves from a water cage, and swim to the shore. Along the way are mystery sacks that may contain items that are useful in any way during their stay in the island which they could retrieve at their discretion. Upon reaching the shore, the castaways must first bind themselves with their respective partners. After that, they must hit the containers hung onto a tree using a long bamboo stick. Inside two of those containers each contain two immunity bracelets. When a pair finds the immunity bracelets, they must run to the flag to finish the game. The first two pairs to have the immunity bracelets wins the Reward Challenge. Reward: Immunity bracelet Tribal Reward/Immunity Challenge: Six climbers must climb several A frames, bringing with them three abaca ropes. Before climbing to the next A frame, all the members of the tribe must be completed and should station themselves on a designated mat. They would repeat this sequence until the tribe had reached the last mat. After the climbers had completed the A frame obstacle, they needed to carry a crate to a starting point (in a form of another mat) for the next part of the challenge. When the tribe had reached the starting point, they need to tie the crate using the rope that they brought along with them. After that, they would put the crate in a long sliding platform, and pull it until it reached the other three members of the tribe who are assigned to solve a puzzle located inside the crate. The first tribe to finish the puzzle and reading aloud its contents wins reward and immunity. Reward: Shelter materials, flint, and a hammock Temptation Reward: Immunity bracelet for each member of the pair. Temptation Consequence: One member must transfer to the opposing tribe. If one member would be voted out in a Tribal Council, the partner would have to be eliminated as well.

Day 1: After undergoing a mud ritual, the castaways were put on a water cage, of which was meters away from the shore. Host Richard Guttierez arrived via seaplane and introduced them to the game and to their first challenge. In the challenge, many of the castaways prioritized looking for the necklaces rather than gathering supplies. The Philippine Volcanoes pair of Arnold & John and former love team Isabel & Chuckie were first to retrieve the necklaces. The castaways then inspected the supplies they gathered during the challenge. Through a schoolyard pick, the two tribes were formed. The Volcanoes duo, the first two members of Bulan, were joined by dating partners Gino & Stef, ex-couple KC & Geneva, mother and daughter Maribel & Mara, and friends Alyssa & Aifha. On the other hand, Isabel & Chuckie's tribe Tala had cousins Carlo & Arthur, couple Ellen & Filo, friends Jackie & Angelicopter, and comedic duo Betong & Maey as its members. The tribes were then directed to their camps, where they started to gather food and build shelter. At Bulan, as the rest of the tribe worked, Gino saw the Volcanoes making alliances with KC. KC was also able to make fire using only bamboo, something the entire Tala tribe were not able to achieve after several tries. Although still early, tribal life had already started to take its emotional toll on Geneva and Aifha, with Geneva already airing her intention to quit. In the evening, a remark by Aifha caused an argument between her and Alyssa.

Day 2: As tribal life went on in Bulan, Geneva was still stressed and was crying. After KC answered to the producer that he wanted to continue the game alone, Geneva decided to quit after having an argument with KC and with the resident psychologist about the ethics of the game. However, the producers decided to give KC the chance to stay in the game as a solo contestant. Difficulties faced by Bulan en route to the challenge area due to the weather and emerging swells forced the producers to postpone the challenge to the next day.

Day 3: In the Reward/Immunity Challenge, Bulan initially led up to the puzzle part, where Tala caught up. Maribel already had the answer to the puzzle, Tagumpay ng isa ay tagumpay ng lahat ("The success of one is the success of all"), while her tribe's puzzle was still unfinished. This enabled Tala to overtake Bulan and complete their puzzle, winning the challenge. After Bulan left, Tala was told of the Temptation Reward. After much deliberation, the tribe chose Angelicopter and Jackie, who stayed behind to see the temptation reward. After weighing their options and their tribe's welfare, the two decided not to accept the temptation and returned to camp, where they discussed about the temptation reward and why they did not accept it. At Bulan, upon noticing a large beehive near camp and the size of the bees that inhabited it, the tribe decided to move their camp to a safer location. At Tala, after several tries using their flint, the tribe finally had a small flame which petered out moments later, forcing the tribe to spend their third straight night without fire. Back at Bulan, after the tribe had a brief mock fire dance to amuse themselves, Maribel apologized to her tribemates about what happened during the Reward/Immunity Challenge. She also expressed wanting to come back to her comfort zone, being the oldest in the tribe.
