The 1976 Isle of Man TT was the fifth round of the 1976 Grand Prix motorcycle racing season held on the Isle of Man between 7 June and 12 June 1976.

The racing would be the final time the Isle of Man TT was an official round on the Grand Prix calendar.

Bowing to pressure for increased rider safety at racing events, FIM moved the Grand Prix to England in 1977 with the British Grand Prix being held at the Silverstone Circuit.

However the Isle of Man TT, as it had before 1949 continued as a stand-alone event.

NOTE: The Isle of Man TT was removed from the international calendar and replaced by a proper British motorcycle Grand Prix.
