Siler is an unincorporated community in Whitley County, Kentucky, United States. The community is located along Kentucky Route 92 east-southeast of Williamsburg. Siler has a post office with ZIP code 40763, which opened on October 5, 1904. It is located within the Bell, Knox, and Whitley tri-county area.
History The community was established in the late 19th century, likely taking its name from a local family of early settlers. Its development was tied to the broader expansion of rural settlements throughout southeastern Kentucky during that period.
In the early 20th century, Siler served as a small local hub supporting nearby coal operations in the region. While not a major mining center itself, the community provided housing and basic services for workers involved in coal extraction and transportation in surrounding areas. The establishment of a post office in 1904 marked Siler's emergence as a recognized settlement.
Throughout the mid-20th century, Siler remained a small, rural community, with its economy connected to agriculture and the declining coal industry. Today, it continues to exist as a quiet residential area within Whitley County.
