John Gallagher (born 17 April 1981) is a Scottish professional golfer who plays on the Tartan Pro Tour.

Young John grew up playing at a modest local golf club and taught himself the game without the benefit of even one lesson.

After his semi-final victory over heavily favored Lloyd Saltman the relatively unknown golfer was suddenly one match away from claiming one of the top two amateur titles in the world and earning coveted invitations to the Masters Tournament and The Open Championship.

Irishman Brian McElhinney, however, got ahead early in their final match and Gallagher could never mount a serious charge in the blustery conditions.

Participating in Scotland's victory at the Home Internationals over Ireland, Wales, and a very strong English contingent capped off his breakthrough 2005 season.

Several strong finishes in 2006 including victory in the Tennant Cup saw Gallagher again briefly break into the top 50 of the worldwide amateur golf ranking.

On the second day he was again three under par through 16 holes at the demanding Loch Lomond course and appeared atop the second page of the leader board.

This outstanding performance (save the last two holes), solidified his confidence in his ability to compete in the professional ranks which he joined in 2009.

Three weeks later, he again recorded a 67 in the opening round, this time at the Virgin Atlantic 25th Anniversary Classic at Marriott Tudor Park.

Gallagher finished the 2009 season 69th on the PGA EuroPro Tour order of merit and was 93rd in 2010 while playing in just 9 events.
