Ronald S Lauder (b. February 26, 1944) was the United States Ambassador to Austria 1986-87.

He is President of the World Jewish Congress. According to Forbes Magazine, his net worth is $3.8 billion as of 2014.
Lauder was born in New York City, the second son of Joseph Lauder, a Presbyterian, and his wife Estée Metzner, a Hungarian Jewess who made her fortune in perfumes and cosmetics under her married name. She had her children raised in her faith.
Lauder was President Ronald Reagan's appointment as US Ambassador to Austria, where he served 1986-1987. He was later a Republican Party candidate when he made a bid to become the mayor of New York City in 1989, losing to Rudy Giuliani in the Republican primaries. Michael Massing, writing of this mayoral election contest, said that politically Lauder "seemed out of step with most American Jews; ... he ran to the right of Rudolph Giuliani. And, on Israeli issues, he was a vocal Likudnik, with long-standing ties to Benjamin Netanyahu".
