Concentration is an American television game show based on the children's memory game of the same name. It was created by Jack Barry and Dan Enright. Contestants matched prizes hidden behind spaces on a game board, which would then reveal portions of a rebus puzzle underneath for the contestants to solve.

The show was broadcast on and off from 1958 to 1991, presented by various hosts, and has been made in several different versions. The original network daytime series, Concentration, appeared on NBC for 14 years, 7 months, and 3,770 telecasts (August 25, 1958 – March 23, 1973), the longest continuous run of any game show on that network. This series was hosted by Hugh Downs and later by Bob Clayton, but for a six-month period in 1969, Ed McMahon hosted the series. The series began at 11:30 am Eastern, then moved to 11:00 and finally to 10:30. Nearly all episodes of the NBC daytime version were produced at 30 Rockefeller Plaza, New York City.

A weekly nighttime version appeared in two separate broadcast runs: the first aired from October 30 to November 20, 1958, with Jack Barry as host, while the second ran from April 24 to September 18, 1961, with Downs as host. The second version of Concentration, the first to be made in Southern California, ran in syndication from September 10, 1973, to September 8, 1978, with Jack Narz as host and Paola Diva as model. The last version of the show to air was Classic Concentration, which ran on NBC from May 4, 1987 to September 20, 1991. Alex Trebek was the host of this version, with Diana Taylor and Marjorie Goodson-Cutt as models.
