Joseph Theophilus "JT" Mears (1871 - October 1935), was an English businessman, most notable for co-founding Chelsea Football Club.
In 1896, Mears and his brother Gus purchased the Stamford Bridge Athletics Ground and went on to found Chelsea Football Club in 1905. Though he was never chairman, Joseph was the "dominant influence" at the club after the death of his brother in 1912  with his son, Joe, and grandson, Brian, both later serving as chairman of the football club.
In 1919 he formed his business into Joseph Mears Launches & Motors Ltd, and acquired a garage in Richmond, along with several motor coaches. The company continued until 1945, when it passed to a newly formed company, Thames Launches Ltd.
He formed Joseph Mears Cinemas Ltd which built up a group of cinemas around the Richmond area.
Mears was Mayor of Richmond from 1931 to 1932.
