Samuel Sinyangwe is an racial justice activist and policy analyst. Sinyangwe is a member of the Movement for Black Lives and a co-founder of Mapping Police Violence, a database of police killings in the United States, and Campaign Zero, a policy platform to end police violence.

As protests emerged in the wake of 2014 shooting of Michael Brown in Ferguson, Missouri, Sinyangwe connected with Ferguson activists DeRay Mckesson and Johnetta Elzie to develop policy solutions to address police violence in America. Together, they built a database of police killings, Mapping Police Violence, and a platform of policy solutions to end police violence called Campaign Zero.

During the 2016 U.S. Presidential campaign, Sinyangwe and colleagues met with Democratic candidates Bernie Sanders and Hillary Clinton on these policy issues. He has also been a vocal critic of the "Ferguson Effect", using data to debunk the premise of this theory.

He has been featured on CNN, MSNBC, BBC News, FiveThirtyEight, The Los Angeles Times, and has written for the Huffington Post and The Guardian.

Sinyangwe graduated from Stanford University, where he studied how race intersects with American politics, economics, and class.
