"We were not friends," Clinton, a former New York senator, told People magazine for a story published Wednesday. "We knew each other, obviously, in New York. I knew a lot of people."
Several Republicans have prodded Trump for his closeness to the Clintons, pointing to their attendance at his wedding and his donations to the Clinton Foundation.
Their daughters, Ivanka Trump and Chelsea Clinton, have remained close during the campaign, with Chelsea telling People in an interview before the Iowa caucuses that "friendship" overcomes politics.
Hillary Clinton, the Democratic front-runner, said during the interview she was "concerned" about the tone of the presidential race, singling out Trump's divisive comments about minorities.
Trump has unloaded on Clinton during the presidential race, accusing her last month of being an "enabler" of her husband's past infidelity.
But he has previously praised the former secretary of State, telling Fox News in 2012 that he thought she was "a terrific woman."
"I am biased because I have known her for years. I live in New York. She lives in New York. I really like her and her husband both a lot," he said.
