Jesse Greene "Jay" Jackson (November 4, 1918 – August 16, 2005) was an American radio and television quiz show host and announcer.

Jackson was the master of ceremonies of the panel quiz show Twenty Questions when it aired on the ABC Television Network starting in early 1953 and ending in May 1955.

When the quiz show scandals exploded in 1958, among the materials a federal grand jury investigated was a series of 1957 Tic-Tac-Dough episodes hosted by Jackson and preserved on kinescope, featuring U.S. Army captain Michael O'Rourke winning over $140,000 during his reign as champion.

Jackson himself was never accused of any wrongdoing; it was noted that he left the show well before the investigations began in earnest.

After leaving Tic-Tac-Dough Jackson never hosted another quiz or game show, though he did narrate a series of Robert Youngson compilations during the 1960s.
