Thomas Donald Meek (14 July 1878 – 18 November 1946) was a Scottish-American actor. He first performed publicly at the age of eight and began appearing on Broadway in 1903. Meek is perhaps best known for his roles in the films You Can't Take It with You (1938) and Stagecoach (1939). He posthumously received a star on the Hollywood Walk of Fame in 1960.

Meek was born in Glasgow to Matthew and Annie Meek. In the 1890s, the Meek family emigrated to Canada and then to the United States. By 1900, they were living in Philadelphia where Meek was employed as a dry goods salesman, according to the United States census of that year with Meek later working on stage.
