Brian Merritt Moehler (born December 31, 1971 in Rockingham, North Carolina) is a starting pitcher, who is currently a free agent.

Moehler pitched for the University of North Carolina at Greensboro and was selected by the Detroit Tigers in the sixth round of the 1993 draft, who assigned him to the Niagara Falls Rapids. After the 1993 season, Moehler moved on to the Jacksonville Suns, where he pitched until late 1996, when he was called up the Tigers.

Moehler pitched for Detroit from 1996 through 2002, and he was the starting pitcher for the Tigers' inaugural game at Comerica Park in 2000. During his stint with the Tigers, he accomplished an amazing feat by winning both the last game at the old Tiger Stadium and the first game at the new Comerica Park. He went on to pitch for the Cincinnati Reds in 2002, the Houston Astros in 2003, and the Florida Marlins 2005-2006. In 1999, during his stint with Detroit, he gained national media attention when he got caught scuffing the baseball against the Tampa Bay Rays, and was suspended for 10 games.

On January 19, 2007, Moehler signed a one-year contract with the Houston Astros; at the end of spring training he earned a relief spot on the roster. On August 2, 2007, Moehler achieved his first save in a Major League game against the Atlanta Braves.
