Clem Simich is a New Zealand politician. He is a member of the National Party. He was first elected to Parliament in the 1992 by-election in Tamaki , prompted by the retirement of former Prime Minister Robert Muldoon. He has remained MP for Tamaki since that point. In August 1998, he was appointed to Cabinet, being Minister of Police, Minister for Racing, and Minister in Charge of the Audit Department. He also became Minister of Corrections in January 1999. He lost his ministerial positions, however, when National lost the 1999 elections.

Simich currently serves as Assistant Speaker of the House. On the retirement of Jonathan Hunt, Simich stood for election as Speaker, but was defeated by Labour's Margaret Wilson. It is likely that he would become Speaker if National were to win the next elections.
