Frank Edward Secory (August 24, 1912 – April 7, 1995) was an American left fielder and umpire in Major League Baseball who played 186 games from 1940 to 1946 with the Cincinnati Reds, Detroit Tigers, and Chicago Cubs.

His career was sidetracked, however, when he fractured his leg sliding into home on May 10 of the following year while with the Syracuse Chiefs, as he had been expected to shortly be promoted to the Reds.

[3] Secory was a National League (NL) umpire from 1952 to 1970, and worked in the World Series in 1957, 1959, 1964 and 1969, serving as crew chief in 1964.

[5] On August 24, 1960, Secory's 48th birthday, while he was umpiring a game at the Los Angeles Coliseum, Los Angeles Dodgers sportscaster Vin Scully unexpectedly invited fans listening to the game radio broadcast at the stadium to yell, "Happy Birthday, Frank!"

Secory tied Bob Emslie's NL record of eight no-hitters on May 1, 1969, when he worked second base in Don Wilson's 4–0 gem;[7] after Augie Donatelli also tied the record later that year, Secory broke it by working in his ninth no-hitter on June 12, 1970, officiating at first base in Dock Ellis' 2–0 win.
