Achille Occhetto (born 1936) is an Italian political figure.

He served as the secretary-general of the Italian Communist Party between 1988 and 1994 (which became the Democratic Party of the Left halfway through his term in 1991, also known as the PDS, and is now part of the Democrats of the Left).

In 2004, Occhetto was elected to the European Parliament on a joint ticket with anti-corruption campaigner Antonio Di Pietro — but he immediately resigned (to be replaced by Giulietto Chiesa, a former communist journalist).
