Frank Joseph Riccelli (born February 24, 1953 in Syracuse, NY) is a former Major League Baseball pitcher. He pitched parts of three seasons in the majors; 1976 for the San Francisco Giants, and 1978-79 for the Houston Astros.

Frank attended Christian Brothers Academy in DeWitt, New York where he was a high school baseball standout. He was named three times to the All-Central New York team. As a junior in 1970, he had an earned run average of 0.74 and 140 strikeouts in 73 innings. As a senior in 1971, he struck out 139 batters in 65 innings. He was selected by the San Francisco Giants with the eighteenth pick of the 1971 MLB Draft, ahead of future Hall of Famers George Brett and Mike Schmidt.

Riccelli began his professional career in Montana in 1971 with the Great Falls Giants. In 1972, with the Amarillo Giants, he had 16 and 17-strikeout games en route to a 183-strikeout season, a total he would not top again in any one year.

On September 11, 1976, Frank made his Major League debut. He and Bob Knepper, who had debuted the day before, became the first starting pitchers in San Francisco Giants history to make their debuts in consecutive games. Frank finished the season in the Major Leagues before returning to the Triple-A Phoenix Giants for the entirety of the following season.

On October 25, 1976, Riccelli was traded to the St. Louis Cardinals for a player to be named later. On June 8, 1978, the Cardinals sent Frank to Houston for Bob Coluccio. Frank would appear in two games for the Astros that year, pitching three scoreless innings. During a start in 1979, he suffered an injury which required him to undergo Tommy John surgery. He returned to baseball with the Pittsburgh Pirates and Toronto Blue Jays organizations in 1980 and 1981 respectively but never returned to the Major Leagues.

He later pitched for the Gold Coast Suns in the Senior Professional Baseball Association and in 2012 he was inducted into the Christian Brothers Academy Hall of Fame.
