Ramón Segundo Monzant Espina (January 4, 1933 – August 10, 2001) was a Venezuelan right-handed baseball pitcher in Major League Baseball (MLB) who played his entire career for the New York / San Francisco Giants from 1954 to 1960.

Monzant was promoted to the Minneapolis Millers in 1954, and pitched in 27 games for the team, winning 11 and losing 7.

One of his best performances took place on April 29, 1956, in a Giants 8–1 complete game victory over the Philadelphia Phillies, when a one-out, first-inning single by Del Ennis cost him a no-hitter.

In 1959, citing a sore arm and a desire to sit out the season, wishing to return to Venezuela, Monzant retired from baseball.

During the season, he broke his leg while sliding into second base, which led to his retirement from baseball for good.
