The 1967 Newark riots involved violent, armed conflict in the streets of Newark, New Jersey. Taking place over a four-day period (between July 12 and July 17, 1967), the Newark riots resulted in at least 26 deaths and hundreds more serious injuries. Serious property damage, including shattered storefronts and fires caused by arson, left many of the city's buildings damaged or destroyed. At the height of the conflict, the National Guard was called upon to occupy the city with tanks and other military equipment, leading to iconic media depictions that were considered particularly shocking when shared in the national press. In the aftermath of the riots, Newark was quite rapidly abandoned by many of its remaining middle-class and affluent residents, as well as much of its white working-class population. The large amount of violence led to accelerated flight, followed by a decades-long period of disinvestment and urban blight, including soaring crime rates and gang activity.

The Newark riots represented a flashpoint in a long-simmering conflict between elements of the city's then-growing African-American population, which had recently become a numerical majority, and its old political establishment, which remained dominated by members of non-African ethnic groups (especially Italian, Jewish, and Irish Americans) who had gained a political foothold in Newark during earlier generations. Endemic corruption in local government, combined with widespread racial prejudice, likely contributed to the city's failure, during the leadup to 1967, to include a more representative cross-section of the city's black population in its political power structure. The Newark riots were part of a larger national phenomenon, being among more than 150 race riots that occurred in the United States in the "Long Hot Summer of 1967". Some historians, focusing on the protest element of the conflict, have termed it the 1967 Newark Rebellion.

Deindustrialization and suburbanization were major contributors to changes in Newark's demographics. White middle-class residents left for other towns across North Jersey, in one of the largest examples of white flight in the country. Between 1960 to 67', the city switched from 65% White to 52% Black and 10% Cuban and Puerto Rican. Due to the legislation of the Servicemen's Readjustment Act of 1944, increasing numbers of white veterans, who had recently returned from fighting in World War II, emigrated from Newark to the suburbs where there was improved access to interstate highways, low-interest mortgages, and colleges. The outflow suburban sprawl of white veterans from Newark was rapidly replaced with an influx of black people moving into the Central Ward; blacks, however, faced discrimination in jobs and housing, ultimately making their lives more likely to fall into a cycle of poverty. By 1967, Newark was one of the United States' first majority-black cities, but was still controlled by white politicians.

Racial profiling, redlining, and lack of opportunity in education, training, and jobs led the city's African–American residents to feel powerless and disenfranchised. In particular, many felt they had been largely excluded from meaningful political representation and often subjected to police brutality.

Newark established a Community Relations Bureau in their police department as early as March 1966. Newark's Police Department director, Dominick Spina, rejected the budget request as he thought it would not be approved. This was much to the disliking to the residents of the Central Ward and it led to more tensions growing in the area as residents saw that in cases of police brutality on black residents, the police would not be held accountable.

Unemployment and poverty were very high, with the traditional manufacturing base of the city having been fully eroded and withdrawn by 1967. Further fueling tensions was the decision by the state of New Jersey to clear tenement buildings from a vast tract of land in the Central Ward to build the new University of Medicine and Dentistry. Thousands of low-income African American residents were displaced at a time when housing in Newark was aging and subjected to high tax rates.^{[citation needed]} Later reports also pointed to Hassan Jeru-Ahmed as a possible agitator in the days leading up to the riots.

Many African Americans, especially younger community leaders, felt they had remained largely disenfranchised in Newark, despite massive changes in the city's demographic makeup. Mayor Hugh J. Addonizio – to date the last white mayor of the city – took few steps to adjust to the changes and provide African Americans with civil leadership positions and better employment opportunities.^{[citation needed]}

Despite being one of the first cities in the country to hire black police officers, the department's demographics remained at odds with the city's population, leading to poor relations between black people and the police department. Only 145 of the 1,322 police officers in the city were black (11%), mirroring national demographics, while the city grew to be over 50% black. Black leaders were increasingly upset that the Newark Police Department remained dominated by white officers, who would routinely stop and question black youths with or without provocation. The riots in Newark occurred two years after riots in Los Angeles and came at a time when racial tensions were high. Historians believe that the shrinking of the economy, increased unemployment, and a city with a majority African American population which was being run by white politicians increased tensions during that era.
