Patrick Mortensen (born 13 July 1989) is a Danish professional footballer who plays as a striker for Danish Superliga club AGF and the Denmark national team.
Progressing through the youth academies of various clubs on Amager, Mortensen made his senior debut for the flagship team on the island, Fremad Amager, in October 2006, before being signed as an emerging talent by Danish Superliga club Brondby the following year. He never managed to break through to their first team, and as a result moved to Lyngby Boldklub, where he developed into a natural goalscorer. In 2015, he signed with Norwegian Tippeligaen club Sarpsborg 08, where he was part of their successful UEFA Europa League campaign in the 2018–19 season, reaching the group stage. He returned to Denmark in January 2019, and signed with AGF. In his second season there he scored 17 league goals, finishing runner-up to the top scorer title as the club finished in third place.
Mortensen has gained 7 caps for the Denmark U21 team, in which he scored two goals. In November 2020, he was called up to Kasper Hjulmand's senior squad for the first time.
