Daniel Reid Topping (June 11, 1912 – May 18, 1974) was a part owner and president of the New York Yankees baseball team from 1945 to 1964.

During Topping's tenure as chief executive of the Yankees, the team won 14 American League pennants and ten World Series championships.

[1] He worked in banking for a few years, opened and closed a small advertising agency, then purchased a partial interest in the Brooklyn Dodgers of the National Football League in 1931.

He became the majority owner of the club and improved the team, but the onset of World War II caused several players to join the military.

MacPhail invited Topping to join the syndicate attempting to purchase the team from the estate of Jacob Ruppert.

Tim Mara, owner of the New York Giants, who played in the Polo Grounds, held NFL territorial rights, and refused to permit this.

Topping moved his team to Yankee Stadium anyway, joining the newly formed All-America Football Conference.

After a drunken episode at the Biltmore at a Yankees 1947 World Series celebration dinner, MacPhail sold his share of the team to Topping and Webb for $2 million.

Dan Topping was then married to three-time Olympic figure skating gold medalist Sonja Henie from 1940 to 1946.
