Setti Warren passed away in late October 2025, leaving behind a lasting legacy of leadership, kindness, and commitment to public service. The former mayor of Newton, Massachusetts, and respected public policy expert was 54 years old. His family confirmed that he died after a courageous battle with cancer — a fight he faced with quiet strength and dignity.
News of his passing brought an outpouring of tributes from across Massachusetts and beyond. Friends, colleagues, and community members described him as a man of principle who always led with empathy and purpose.
A Lifelong Dedication to Service
Born in 1970 in Newton, Massachusetts, Setti David Warren spent much of his life serving the community that raised him. He attended Newton public schools, earned his degree from Boston College, and later completed a law degree at Suffolk University Law School.
From a young age, Warren believed in the power of government to help people. That belief guided him through a career that spanned local politics, federal government service, military duty, and academia.
Before running for office, Warren worked in Washington, D.C., as a special assistant in the Clinton administration’s Office of Cabinet Affairs. There, he helped coordinate policies between the White House and federal agencies — an experience that deepened his understanding of how national decisions affect local communities.
Serving His Country: A Veteran’s Commitment
Warren’s sense of duty extended beyond politics. He served as an intelligence specialist in the U.S. Navy Reserve and was deployed to Iraq during Operation Iraqi Freedom. His time in uniform strengthened his dedication to teamwork, discipline, and public service.
Friends and fellow service members remembered him as calm under pressure and deeply loyal to his team. After returning home, he continued to advocate for veterans, focusing on programs that helped them transition to civilian life and find employment.
His military service shaped his leadership style — steady, thoughtful, and driven by integrity.

In 2009, Setti Warren made history when he was elected as the first Black mayor of Newton. His victory marked a turning point in the city’s political history and inspired countless young people across Massachusetts to see leadership as something they, too, could achieve.

Warren often said that leadership was about “listening more than talking.” Residents recall how he would attend community meetings, listen carefully to local concerns, and respond with thoughtful, practical solutions.
A Run for Massachusetts Governor
After two successful terms as mayor, Warren announced his candidacy for Governor of Massachusetts in 2017. His campaign focused on fairness, economic opportunity, and better transportation systems.
He openly addressed the state’s widening wealth gap, calling for bold ideas to ensure that every community — not just Greater Boston — could prosper. Although he ended his campaign in 2018 due to funding challenges, many political observers praised his honesty and courage.
His campaign helped set the stage for broader conversations about inequality and regional investment that continue in Massachusetts politics today.
A New Role at Harvard Kennedy School
Following his mayoral career, Setti Warren joined Harvard Kennedy School as the Executive Director of the Institute of Politics (IOP). In that role, he mentored students, helped design leadership programs, and guided discussions about civic engagement and bipartisanship.
Students admired him for his authenticity and accessibility. Many described him as the kind of leader who remembered everyone’s name and took time to ask about their goals.
Under his guidance, the IOP expanded its efforts to include underrepresented voices and tackle real-world challenges, from climate change to local government reform.
Warren’s impact at Harvard extended far beyond the classroom — he inspired young people to see politics not as power, but as a way to serve.
A Champion for Equity and Inclusion
Equity was at the center of everything Setti Warren did. Whether as mayor, candidate, or educator, he believed in creating opportunities for all.
He worked to expand affordable housing, close educational gaps, and ensure that public policies reflected the needs of everyone — not just the privileged few. Warren’s approach was always pragmatic and human-centered. He believed government could be both compassionate and efficient.
His colleagues described him as a “solutions-oriented” leader who focused less on politics and more on outcomes. For Warren, progress was never about headlines — it was about people.
