Robert Kagan (born September 26, 1958) is an American historian, author, columnist, and foreign-policy commentator. Kagan is mainly characterized as a leading neoconservative, but he prefers the term "liberal interventionist" to describe himself. Some have characterized him as a realist.

A co-founder of the neoconservative Project for the New American Century, he is a senior fellow at the Brookings Institution and a member of the Council on Foreign Relations. Kagan has been a foreign policy adviser to U.S. Republican presidential candidates as well as Democratic administrations via the Foreign Affairs Policy Board. He writes a monthly column on world affairs for The Washington Post, and is a contributing editor at The New Republic. Kagan left the Republican Party in 2016 due to what he described as Donald Trump's fascism, and endorsed Hillary Clinton.
