Sumbul Siddiqui is currently serving her fourth term on the Cambridge City Council. Previously, she served two terms as Mayor of Cambridge—becoming the first Muslim mayor in Massachusetts and the first woman to serve two consecutive terms in the role.

During her time as mayor, she led Cambridge through the COVID-19 pandemic with a focus on equity and innovation. She raised more than $5 million in emergency relief for residents and small businesses, while strengthening food access, housing protections, and health services. She also launched the Cambridge RISE guaranteed income pilot, which grew into a $22 million program supporting 2,000 families, helping to shape the national conversation on direct cash assistance. Sumbul has led efforts for universal pre-kindergarten, established an Early College program at Cambridge Rindge and Latin School, and helped pass major zoning reforms to increase affordable housing. Before serving in elected office, Sumbul worked as a legal aid attorney in Lawrence, Lowell, and Lynn.

Sumbul was born in Karachi, Pakistan, and immigrated to the United States as a child with her parents and twin brother. She lived in Cambridge in affordable housing, which deeply shaped her commitment to public service. After moving around for college and law school, Sumbul is now back living in Cambridge where she enjoys spending time with her family and their cat, Willow.
