Lionel Blair (born 1931 or 1934 in Montreal, Canada) (real name Lionel Ogus) is a British actor, choreographer, tap dancer and television presenter. He is best known in Britain for being a team captain on the gameshow Give Us A Clue from 1982 until the early 1990s and also for being the (second) presenter of the British version of popular game show Name That Tune in the 1980s.

Blair's rather camp image first came to the fore in the 1960s, when, with his own dance troupe, he appeared on many television variety programmes. He also appeared in films such as A Hard Day's Night and Absolute Beginners, and in television comedy, including the classic short film, The Plank . In addition, he choreographed films such as Jazz Boat (1960) and The Magic Christian (1969).

In many episodes of the Radio 4 show I'm Sorry I Haven't A Clue the presenter makes a comment about Blair during the 'Sound Charades' round, a radio adaptation of Give Us A Clue, with innuendo such as:

The most highly skilled of all was Lionel Blair. I can still remember how the tears of frustration welled up in his eyes during their Italian tour at not being allowed the use of his mouth to finish off Two Gentlemen of Verona.
