Marilyn Cochran Brown (born February 5, 1950) is a former World Cup alpine ski racer from the United States.

The eldest of four siblings of the "Skiing Cochrans" family of Richmond, Vermont, she became the first American to win a discipline championship in the World Cup, triumphing in giant slalom at age 19 in 1969.

She made her World Cup debut at age 18 in March 1968, a month after the Winter Olympics, with a pair of top ten finishes at the season's final stop in Aspen, Colorado.

[1] Cochran was the only American alpine racer with a World Cup season title until 1980, when Phil Mahre won the combined.

At the World Championships in 1974 in Switzerland, Cochran finished eighth in giant slalom, and retired from international competition after the season.
