Bernd Klaus Wiesberger ([bɛʁnt ˈviːsˌbɛʁɡɐ]; born 8 October 1985) is an Austrian professional golfer who plays on the European Tour and formerly on the LIV Golf League.

He was unable to win enough money during his rookie season to retain his card and returned to the Challenge Tour.

In July 2012, Wiesberger won his second title of the year and of his European Tour career at the Lyoness Open, held in his home country of Austria.

In May 2015, Wiesberger lost in a three-man sudden-death playoff at the Dubai Duty Free Irish Open.

On 5 July Wiesberger would win his third event on the European Tour when he took the Alstom Open de France.

In the playoff, Wiesberger found trouble from the tee, but hit his approach to within five feet for birdie to claim victory.

[8] On 14 July 2019, he won the Aberdeen Standard Investments Scottish Open at Renaissance Club in North Berwick, Scotland.

Four weeks later he followed that with a tied-for-fifth-place finish at the BMW International Open, to increase his chances of a selection to the 2021 European Ryder Cup team.

The U.S. team won 19–9 and Wiesberger went 0–3–0 including a loss in his Sunday singles match against Brooks Koepka.
