11P/Tempel–Swift–LINEAR is a periodic comet in our solar system.

Ernst Wilhelm Leberecht Tempel (Marseille) originally discovered the comet on November 27, 1869, it was later observed by Lewis Swift (Warner Observatory) on October 11, 1880 and realised to be the same comet.

After 1908 the comet became an unobservable lost comet, but on December 7, 2001 an object was found by the Lincoln Near Earth Asteroid Research (LINEAR) program, and confirmed by previous images from September 10 and October 17 as being the same comet.
