Ulf Ivar Erik Sterner (born 11 February 1941) is a Swedish former professional ice hockey forward.

He played in nine IIHF World Championships for Sweden, where the team won seven medals: one gold, five silver, and one bronze.

On 12 November 1959, he made his international debut with Tre Kronor in a friendly match against Czechoslovakia's team.

After the game, he and teammate Sven "Tumba" Johansson met King Gustaf VI Adolf and received a royal congratulations.

The parties signed a five-game tryout agreement, but Sterner declined to play that season to conserve his amateur status for the 1964 Winter Olympics.

The Swedish Olympic hockey team won a silver medal, and Sterner then attended the NY Rangers training camp in 1964 where he displayed excellent skills.

After two months, he had adapted to the different style of play and was promoted to the Baltimore Clippers of the American Hockey League.
