Noreen M. Corcoran (October 20, 1943 – January 15, 2016) was an American actress, dancer, and singer best known for her co-starring role in the television sitcom Bachelor Father, as the teenager Kelly Gregg, the niece of wealthy attorney Bentley Gregg, played by John Forsythe.
Corcoran was the third of eight children born in Quincy, Massachusetts, to William "Bill" Corcoran, Sr. (1905–1958), and the former Kathleen McKenney (1917–1972). In 1947, the Corcorans moved to Santa Monica, California, where the father became the maintenance chief at Metro-Goldwyn-Mayer.
The Corcoran children studied dramatics or dance as a means to launch potential acting careers. During the 1950s, Noreen's younger brother Kevin Corcoran gained fame in the role of Moochie on Walt Disney's The Adventures of Spin and Marty with Tim Considine and David Stollery, and in the serial Moochie of the Little League on Walt Disney Presents. Several of Noreen and Kevin's siblings, including Kelly (1958-2002), were actors.
