Howard Homan Buffett (August 13, 1903 – April 30, 1964) was an Omaha, Nebraska businessman and four-term Republican Congressman from Nebraska.

Buffett attended public schools and graduated from the University of Nebraska in Lincoln, Nebraska in 1925. Entering the investment business, Buffett also served on the Omaha Board of Education from 1939 to 1942. In 1942 he ran for U.S. Representative in the Nebraska disrict in which Omaha was located, winning the Republican nomination in the primary and then the subsequent general election, and was reelected twice. In 1948 he was again the Republican nominee for another term but was defeated for reelection; however he was again the Republican nominee for the office again in 1950 and won the office back. In 1952 Buffett decided against seeking another term and returned to his investment business Buffett-Falk & Co. in Omaha, in which he worked until shortly before his death.

Buffett is probably best-known today as the father of renowned investor Warren Buffett, who is estimated by some authorities to be the world's second-wealthiest individual.
