Ulf Béla Timmermann (German pronunciation: [ʊlf ˈtɪmɐˌman], audioⓘ; born 1 November 1962 in East Berlin) is a German former shot putter who broke the world record several times during the 1980s, and is the first and one of only four people to ever throw over 23 metres (along with Randy Barnes, Joe Kovacs and Ryan Crouser).

Timmermann was born in Berlin to an athletic family and took up shot put at 13.

He won gold for East Germany at the 1988 Olympics in Seoul, ahead of Randy Barnes of the U.S.

The fourth place throw at this competition would have won every previous Olympics in the shot put.

Timmermann is the farthest thrower of all time in the shot put using the glide technique.
