Monty Python Live (Mostly) (also billed as Monty Python Live (Mostly): One Down, Five to Go) was a variety show by the Monty Python comedy group at The O2 in London in July 2014. Planned as a single performance for 1 July, it was expanded to 10 shows due to the high demand for tickets. It was their first live performance together in 16 years, the second without member Graham Chapman (who died in 1989) and the last with Terry Jones (who died in 2020).

The final date was broadcast in cinemas around the world on 20 July. Prior to this Eric Idle stated, "It is a world event and that’s really quite exciting. It means we’re actually going to say goodbye publicly on one show. Nobody ever has the chance to do that. The Beatles didn't get a last good night."
