Melissa Linda "Mo" Martin (born October 8, 1982) is an American professional golfer playing on the LPGA Tour.

Martin won the Women's British Open in 2014, her first major championship and also her first LPGA Tour title.

An eagle at the final hole on Sunday gave her the victory, one stroke ahead of runners-up Shanshan Feng and Suzann Pettersen.

Allen died of a heart attack when Mo was in college at age 20, and she then established a relationship with her paternal grandfather, Lincoln Martin, who was over 90 years old.

Before Allen's death, Mo and Lincoln had minimal interaction, due to a strained father-son relationship.
