At the time of his retirement, Leahy was the dean of Vermont's congressional delegation, Vermont's longest-serving U.S. senator, and the first Democrat ever elected to the U.S. Senate from Vermont. Leahy was succeeded by Peter Welch, who became the second Democrat to represent Vermont in the Senate.

Leahy's signature legislation is the Leahy Law forbidding the United States from funding foreign military units which violate human rights. Leahy was the presiding officer at Donald Trump's second impeachment trial, becoming the first senator to preside over a former president's impeachment trial. In 2023, Patrick Leahy Burlington International Airport was renamed after him.
