Peter Graham Waterfield (born 12 March 1981) is a British former diver and Olympic silver medalist.

Waterfield and Taylor came in fourth at the men's synchronised 10-metre platform in the 2000 Summer Olympics in Sydney.

In the diving events at the 2004 Summer Olympics in Athens, they won the silver medal in the men's synchronised 10-metre platform – Britain's first Olympic diving medal since Brian Phelps in 1960.

In the 2002 Commonwealth Games held in Manchester, Waterfield's best solo showing came when he won the 10-metre gold medal.

Waterfield announced his retirement from diving in July 2013, at the age of 32, following a decision to cut his funding by UK Sport.
