The Trakai Kenesa is a former Qaraite Jewish congregation and synagogue, or kenesa, located at 30 Karaimų Street, in Trakai, in the Vilnius County of Lithuania.
Designed in the Baroque Revival style, the wooden synagogue was completed in c. 1800, restored in the 1890s. Built on a rectangular plan and covered with a hipped roof with a small annex, the synagogue was larger than the surrounding houses. The building is a rare example of one of the surviving kenesas of the former Polish–Lithuanian Commonwealth. The building now operates as a Jewish museum.
