History Approved by voters in 1997, Seneca High School was established as the district's fourth high school. The facility was initially expected to be completed by 2000, constructed on a site designed to accommodate 2,000 students. However, the school ultimately opened in September 2003 with 860 students from Shamong, Southampton, Tabernacle, and Woodland Townships. The total cost of construction amounted to $45.7 million (equivalent to $ million in ), with delays caused by lawsuits related to the building site in the Pinelands resulting in budget overruns of $8.7 million.Daniels, Mike. "Seneca High awaits Students; School will get 860 students from 4 S. J. towns in first year", Courier-Post, August 25, 2003. Accessed March 12, 2022, via Newspapers.com. "Seneca High School, the newest addition to the Lenape Regional High School District, is ready and waiting for students and teachers to fill its hallways, gymnasiums and classrooms. The 255,008-square-foot building sits on 210 acres on Carranza Road.... The school, approved by district voters in a 1997 referendum, will house about 860 students from Tabernacle, Shamong, Southampton and Woodland in its first year. The move to Seneca was mandatory for all incoming ninth- and 10th-graders in the four Pinelands townships.... Enrollment should rise to more than 1,400 within two years, district officials said. The $45.7 million building can hold 1,500 students and was designed to allow for expansion to hold 2,000 students.... The school originally was scheduled to open in 2000. But construction was delayed by a series of legal challenges filed by the nonprofit Pinelands Preservation Alliance and a citizens organization, the Rural Tabernacle Coalition. The legal challenges contributed to the school costing about $8.7 million more than originally planned."Staff. "Hall of Fame to honor Lenape High School student-athletes", Burlington County Times, July 6, 2017. Accessed January 19, 2020. "The schools of the Lenape Regional School District have produced thousands of graduates who have distinguished themselves as stellar athletes over the nearly 60 years since Lenape High School opened in 1958, Shawnee High School in 1970, Cherokee High School in 1975 and Seneca High School in 2003."

The district chose the name "Seneca High School" in December 2000, continuing the practice of assigning Native American names to its schools. Seneca was selected due to its traditional presence in the area. Additionally, the nickname "Golden Eagles" was chosen from a variety of animal-based alternatives, rather than selecting a nickname related to Native Americans, as had been done with the district's three other schools.Daniels, Mike. "New Lenape district high school being named after peaceful Indian tribe", Courier-Post, December 21, 2000. Accessed February 25, 2022, via Newspapers.com. "Chippewa, Blackhawk and Mohican were just a few of the names batted around for the fourth high school in the Lenape Regional High School District... School teams will be nicknamed the Golden Eagles and school colors will be green and gold.... Milich said finding a tribal name with regional roots was important.... The nickname, the Golden Eagles, also departs from tradition. The other three schools all have Native American-based nicknames the Lenape Indians, Shawnee Renegades and Cherokee Chiefs. Hicks said for Seneca, the board considered only animal nicknames."

The opening of Seneca High School allowed enrollment levels at Lenape High School and Shawnee High School to decrease, helping to alleviate the overcrowding both schools had experienced. Based on the number of students who opted to switch to Seneca, the school's first graduating class in 2005 was expected to consist of 150 students.Pearsall, Richard. "Seneca High School forms first graduating class", Courier-Post at SouthJerseyNews.com, November 14, 2002. Accessed January 19, 2020. "The first graduating class at Seneca High School will have about 150 members, barring any last minute rush, school officials say. They are the sophomores of today at Shawnee and Lenape high schools who have opted to transfer to the new high school for its opening next fall.... Students from Tabernacle and Shamong now attend Shawnee High School in Medford, while students from Southampton and Woodland attend Lenape High School, also in Medford, near the Mount Laurel line. Both those schools are overcrowded, which is the reason the Lenape district held a referendum in December 1997 to build the new high school in Tabernacle."
