Markus Brier (born 5 July 1968) is one of relatively few Austrian touring professional golfers, and as of 2008 is his country's highest ranked player.
Brier won the Swiss and German Amateur Opens in the mid 1990s, and turned professional in 1995 at a relatively late age. Nine top ten finishes, including five top threes, on the 1999 Challenge Tour earned him third place on the season ending money list and playing privileges on the European Tour for 2000. He has retained his tour card since then through his final position on the order of merit every year, except for 2002 when he regained it through final qualifying school.
Since joining the European Tour, Brier has continued to play in his home event, the Austrian Open, winning it on two occasions during a period when it was a Challenge Tour event. In 2006 the tournament was promoted back onto the main European Tour schedule, now under the sponsored title BA-CA Golf Open. In its first year back, Brier once again took the title, in the process becoming the first Austrian golfer to win a European Tour event. This win helped him to his then best year-end finish on the Order of Merit of 49th.
