The Protests Against the Killing of George Floyd and for Black Lives were an series of police brutality protests that began in Minneapolis on May 26, 2020. They were an international response to the killing of George Floyd, a 46-year-old African-American man, who was suffocated while in police custory, even as he cried out that he could not breathe. During the arrest, Derek Chauvin, a Minneapolis Police Department officer, knelt on Floyd's neck for nearly eight minutes as three other officers looked on and prevented passers-by from intervening. Chauvin and the other three officers involved were later arrested.

Local protests began in the Minneapolis–Saint Paul metropolitan area of Minnesota before quickly spreading nationwide and to over 2,000 cities and towns in over sixty countries in support of the Black Lives Matter (BLM) movement. Polls in the Summer of 2020 estimated that between 15 million and 26 million people had participated at some point in the demonstrations in the United States, making the protests the largest in the nation's history.

While the majority of protests were peaceful, demonstrations in some cities escalated into riots, looting, and street skirmishes with police and counter-protesters. Some police responded to protests with instances of police violence.

The protests precipitated a cultural reckoning on racial injustice in the United States and led to numerous legislative proposals on federal, state, and municipal levels intended to combat police misconduct, systemic racism, qualified immunity, and police brutality in the United States. The protests, which also led to a wave of monument removals and name changes throughout the world, occurred during the global COVID-19 pandemic and amidst the 2020 United States presidential election season.
