George Floyd protests in Portland, Oregon

Starting in May 2020, protests following the murder of George Floyd were held in the city of Portland, Oregon, concurrent with protests in other cities in the United States and around the world. By July 2020, many of the protests, which had been held every day since May 28, drew more than 1,000 participants. Protests continued into August, September, and October 2020, often drawing hundreds.

While starting out as mostly peaceful demonstrations, by late summer of 2020 riots had exceeded peaceful protests in number and percentage overall. By September 2020, demonstrations often involved arson, property damage (mostly concentrated in Downtown Portland), looting and vandalism. This pattern of escalation occurred gradually over the summer months, with a notable increase following federal intervention at the downtown courthouse. Confrontations became concentrated in specific areas of downtown Portland, particularly near federal buildings and the Justice Center. By late summer, these incidents had affected public perception to the extent that a majority of Oregonians had come to view the events as riots rather than protests. In response, the US deployed BORTAC and the US Marshals, which heated confrontations with law enforcement and counter-protesters, and prompted increased use of tear gas and other weapons. One person was shot and killed in the aftermath of a clash between protesters and counter-protesters.

In early July, the federal government deployed law enforcement officers to Portland for the stated purpose of protecting federal property amid the unrest. The deployment was criticized for not clearly identifying officers and for seizing protesters not on or near federal property, including by Portland's mayor and most of the state's congressional delegation. The U.S. Customs and Border Protection service defended the practice on the grounds of protecting the officers' personal safety. Several lawsuits were filed by and on behalf of journalists and legal observers against local and federal law enforcement, and by the state against several federal agencies.

Protests continued in Portland in the aftermath of the 2020 United States presidential election, as well as after the January 20, 2021 inauguration of Joe Biden. Protests also occurred near the ICE facility, and clashes occurred with police.
