Lawrence Curtis Jackson (June 2, 1931 – August 28, 1990) was an American right-handed professional baseball pitcher, who played in Major League Baseball (MLB) for the St. Louis Cardinals, Chicago Cubs, and Philadelphia Phillies from 1955 to 1968. In 1964, Jackson led the National League (NL) with 24 wins (playing for the eighth-place Cubs), and was runner-up in the Cy Young Award voting; he also led the NL in innings pitched and shutouts, once each. Jackson's 194 career NL victories are the most in the league since 1900 by any right-hander who never played for a first-place team. A model of reliability, he won at least 13 games in each of his last 12 seasons. He later served four terms in the Idaho Legislature.
