The 1943 Detroit race riot took place in Detroit, Michigan, of the United States, from the evening of June 20 through to the early morning of June 22. It occurred in a period of dramatic population increase and social tensions associated with the military buildup of U.S. participation in World War II, as Detroit's automotive industry was converted to the war effort. Existing social tensions and housing shortages were exacerbated by racist feelings about the arrival of nearly 400,000 migrants, both African-American and White Southerners, from the Southeastern United States between 1941 and 1943. The new migrants competed for space and jobs, as well as against European immigrants and their descendants. The riot escalated in the city after a false rumor spread that a mob of whites had thrown a black mother and her baby into the Detroit River. Blacks looted and destroyed white property as retaliation. Whites overran Woodward to Veron where they proceeded to tip over 20 cars that belonged to black families.

The Detroit riots were one of five that summer; it followed ones in Beaumont, TX, Harlem, NY, Los Angeles, CA (the Zoot Suit Riot), and Mobile, AL.

The rioting in Detroit began among youths at Belle Isle Park on June 20, 1943; the unrest moved into the city proper and was exacerbated by false rumors of racial attacks in both the black and white communities. It continued until June 22. It was suppressed after 6,000 federal troops were ordered into the city to restore peace. A total of 34 people were killed, 25 of them black and most at the hands of the white police force, while 433 were wounded (75 percent of them black), and property valued at $2 million ($30.4 million in 2020 US dollars) was destroyed. Most of the riot took place in the black area of Paradise Valley, the poorest neighborhood of the city.At the time, white commissions attributed the cause of the riot to black people and youths but the NAACP claimed deeper causes: a shortage of affordable housing, discrimination in employment, lack of minority representation in the police, and white police brutality. A late 20th-century analysis of the rioters showed that the white rioters were younger and often unemployed (characteristics that the riot commissions had falsely attributed to blacks, despite evidence in front of them). If working, the whites often held semi-skilled or skilled positions. Whites traveled long distances across the city to join the first stage of the riot near the bridge to Belle Isle Park, and later some traveled in armed groups explicitly to attack the black neighborhood in Paradise Valley. The black participants were often older, established city residents, who in many cases had lived in the city for more than a decade, They also looted and destroyed white-owned property in their neighborhood.

Many white rioters were simply defending their property.
