The former secretary of State tops the businessman, 45 to 41 percent.
If third-party candidates are factored in, however, the race is too close to call. Clinton would get 40 percent, pollsters found, to Trump’s 38 percent. Libertarian Party nominee Gary Johnson would take 5 percent, and 3 percent would go to Green Party candidate Jill Stein.
Pollsters also found that both Clinton and Trump are unpopular with most voters.
Fifty-seven percent have a "very unfavorable" or "strongly unfavorable" perception of Clinton. Only 37 percent, meanwhile, have a "strongly favorable" or "somewhat favorable" view of the Democratic presidential front-runner.
Fifty-nine percent view Trump "strongly" or "somewhat" unfavorably, contrasted with 34 percent who say "strongly" or "somewhat" favorably instead.
"This is a very a tight race that will divide Democrats and Republicans, the young and old, white, black and Hispanic voters — and husbands and wives — in the months ahead," said Tim Malloy, assistant director of the Quinnipiac University poll.
"American voters don't like either one of the front-runners," he added. "The question could be who we dislike the least."
Quinnipiac University questioned 1,561 registered voters from May 24 to 30. The poll has a 2.5 percentage point margin of error.
