John Joseph Linehan, MBE (b. 1952, Belfast, Northern Ireland) is better known as the character May McFettridge. He is married to Brenda, and they have two daughters.

John Linehan was a car mechanic before he rose to fame in the guise of his plain-speaking, gap-toothed housewife character, May McFettridge. Eamonn Holmes, a relative, had asked Linehan to phone his then radio show, to liven the programme up. Linehan pretended to be a Belfast housewife, and the banter between the two attracted an unprecedented number of positive phone calls to the radio studio, many asking for a return of the women as a regular on the show.

Linehan invented the name and the character by ad libbing — the first name being that of his mother-in-law and the surname being that of an Antrim hurler by the name of Olcan McFettridge, whose exploits in a National Hurling League game had made headlines in the local newspaper, The Irish News, which happened to be beside Linehan when put on the spot.
