Jonas Fredrik Blixt Berglund (born 24 April 1984) is a Swedish professional golfer who currently plays on the PGA Tour.

He started the PGA Tour Fall Series well with another third-place finish at the Justin Timberlake Shriners Hospitals for Children Open.

In a rare visit to Sweden, he finished runner-up at the European Tour tournament Nordea Masters at Bro Hof Slott Golf Club in June 2013.

Blixt played in the 2014 Masters Tournament, his first visit to Augusta, and finished in a tie for second place with Jordan Spieth, three shots behind Bubba Watson.

On 1 May 2017, Blixt partnered with Cameron Smith to win the Zurich Classic of New Orleans, the first team event on the PGA Tour since 1981.

Blixt barely held onto his PGA Tour card during the 2018–19 season after he finished 124th on the FedEx Cup points list.

Due to medical issues, Blixt only competed in 8 events during the 2020–21 season, and finished 222nd on the FedEx Cup points list.
