Dolan Levon Nichols (February 28, 1930 – November 28, 1989), nicknamed "Nick", was an American professional baseball player, a relief pitcher who worked in 24 games in the Major Leagues for the 1958 Chicago Cubs. A right-hander, the native of Tishomingo, Mississippi, stood 6 feet (1.8 m) tall and weighed 195 pounds (88 kg).
Nichols' stint with the Cubs was largely spent during the early weeks of the 1958 campaign. He registered his four Major League decisions — all losses — between May 4 and June 7. Earlier, on April 23, he earned his only MLB save against the Los Angeles Dodgers, preserving a 7–6 win for Don Elston at the Los Angeles Memorial Coliseum. In 41⅓ MLB innings pitched, Nichols surrendered 46 hits and 16 bases on balls, with nine strikeouts.
Nichols' minor league career lasted nine seasons (1952–1960). He won 80 games, losing 67, for teams in the Cleveland Indians' and Cubs' organizations.
