Martha Kinsey (July 20, 1882 – ) was an American amateur tennis player and golfer in the early part of the 20th century.

She was runner-up in 1907 (to future International Tennis Hall of Fame enshrinee May Sutton), and in 1909 (to Edith Hannam of Great Britain).

She won in 1907 with Ruth Cowing, in 1908 with Dodd, in 1909 with Adele Kruse, and in 1910 with Helen McLaughlin.

She also was a two-time mixed doubles finalist: in 1908 with William Hopple, and in 1910 with P. Lincoln Mitchell.

In the 1920s, she turned in her tennis racquet for a set of golf clubs, becoming one of the best golfers of her age, playing in tournaments across the nation.
