Alexandre Joseph "Lex" Goudsmit (Dutch: [ˈlɛks ˈxʌutsmɪt];[a] 15 March 1913 – 10 December 1999) was a Dutch-Belgian actor.

Goudsmit's father, a diamond worker, was Jewish and his mother Roman Catholic.

He became famous in 1966 for playing Tevye in Fiddler on the Roof, which role he performed some 1100 times in the Netherlands and in London.

Goudsmit was one of the artists who recorded the song Shalom from Holland (written by Simon Hammelburg and Ron Klipstein) as a token of solidarity to the Israeli people, threatened by missiles from Iraq, during the first Gulf War in 1991.

Goudsmit had told producers that he wanted to stay on Sesamstraat even after his death, so the latest scenes he taped were still used on the next season.
