Fiona Ma (born March 4, 1966) is an American politician and accountant. She has been serving as the California state treasurer since January 7, 2019. She previously was a member of the California Board of Equalization (2015–2019), the California State Assembly (2006–2012), and the San Francisco Board of Supervisors (2002–2006).

A member of the Democratic Party, Ma was the first Asian American woman to serve as California Assembly Speaker Pro Tempore, the second highest-ranking office in the California Assembly. Ma is also only the second Certified Public Accountant (CPA) to be elected to the Board of Equalization. She was selected as Chairperson of the California Board of Equalization in 2016, and ordered three external audits of the agency.

In March 2019, Ma announced she would run for the 2026 California gubernatorial election. In March 2023, she announced that she would be running for the 2026 California lieutenant gubernatorial election instead.
