Thomas Francis Ryan (1872 – November 19, 1961) was a Canadian sportsman and entrepreneur who created five-pin bowling.
He is said to have been a baseball pitcher good enough for a professional offer, although the details are sketchy.
Ten-pin bowling had been growing in popularity, but some of Ryan's customers complained that the ball was too heavy.
He later bought the former home of the Massey family, which he converted into an antique gallery and auction house.
He is buried in the Mount Hope Catholic Cemetery in Toronto, Ontario.
