Bjorn Fratangelo (/biˈɔːrn frəˈtændʒəloʊ/ bee-ORN frə-TAN-jə-loh;[1][2] born July 19, 1993) is an American tennis coach and former professional player.

He then moved to Naples, Florida, for training reasons and was an online student of Barron Collier High School.

He reached another final on the ITF Men's Circuit in May 2012, but lost in straight sets to Tennys Sandgren in Tampa, Florida.

He put the wildcard to good use by defeating compatriot Sam Querrey in the first round of the French Open to crack the top 100 for the first time.

At the 2021 US Open, Fratangelo made his debut in mixed doubles with Madison Keys, whom he began dating four years ago.

He secured his main draw spot at the 2022 French Open for a second consecutive year at this major with a straight sets win over Nino Serdarušić.
