That is according to a new survey conducted by the Anti-Defamation League, which found that 35 percent of respondents admitted to being harassed online due to their racial, religious, or sexual identity.
The figure is up by three percent from 2019, suggesting the issue is becoming increasingly problematic.
LGBTQ+ respondents experienced the highest levels of harassment, with as many as 65 percent of respondents from the community admitting they've been harassed online.
Elsewhere, some 42 percent of Muslim respondents have been harassed, and 37 percent of African-American respondents.
Despite this, the research found that for the LGBTQ+ community, harassment levels have fallen from 76 percent in 2019.
And overall, some 44 percent of respondents admitted to being harassed online compared to 53 percent last year.
The survey's authors said: "So, while it may be 'safer' to live online in general this year as compared to last, ultimately, it is harder and less safe to be online as a member of a marginalised group.
"Specifically, LGBTQ+ individuals, Muslims, Hispanics or Latinos, and African-Americans faced especially high rates of identity-based discrimination."
