Dr. Peter Roland Nattrass is a Perth businessman and politician who was the Lord Mayor of the Perth City Council from 1995 to 2007 having succeeded Reg Withers. He was elected to the council in 1977. He was re-elected Lord Mayor in 1999 and again in 2003. His term in the office of Lord Mayor is the longest held for the City of Perth.

Nattrass was succeeded by the first female Lord Mayor of Perth, Lisa Scaffidi on 21 October 2007.

Peter was born to Joyce Nattrass and Roland Nattrass, a consultant gynaecologist in Perth's public hospitals. He attended Hale School, UWA and the RCOG in London. He began private practice in 1975 and entered local politics in 1977. His political career culminated in his election as Lord Mayor of Perth in 1995.

In July 2004, the West Australian newspaper and MLA Larry Graham aired allegations of domestic violence made by Margot Nattrass, his former wife. As a result, the Legislative Assembly voted on a motion to consider whether he was a fit and proper person to hold the position of Lord Mayor. The motion was lost (41/1).

Nattrass is a member of civic and planning commissions, Rotary, the Western Australian Trotting Association and the Royal King's Park Tennis Club and the Royal Perth Yacht Club.

His partner is Liberal member for Curtin and current Deputy Leader of the Opposition, Julie Bishop.
