Protests against Donald Trump have occurred in the United States, Europe and elsewhere since his entry into the 2016 presidential campaign. Protests have expressed opposition to Trump's campaign rhetoric, his electoral win, his inauguration, his alleged history of sexual misconduct and various presidential actions, most notably his aggressive family separation policy. Some protests have taken the form of walk-outs, business closures, and petitions as well as rallies, demonstrations, and marches.

The largest organized protest against Trump was the day after his inauguration; millions protested on January 21, 2017, during the Women's March, with each individual city's protest taken into consideration, makes it the largest single-day protest in the history of the United States.
