Helen Dinsmore Huntington Astor Hull (April 9, 1893 – December 11, 1976) was an American socialite, arts patron, and political hostess.

[9] Huntington was a good friend of Elsa Maxwell, Cole Porter, and Maury Henry Biddle Paul (aka Cholly Knickerbocker).

[13] She was a guest at the United States presidential inaugural balls of four different U.S. presidents: Calvin Coolidge, Herbert Hoover, Dwight D. Eisenhower, and Richard Nixon.

In 1941, Helen inherited Staatsburg on Hudson from her maternal grandfather, William Brown Dinsmore II, head of Adams Express Company, a railroad and shipping concern.

She demolished the previous mansion to build a much lighter house, known as Locusts on Hudson, that was designed by architect John Churchill in the Neobaroque style.

Helen asked Astor to choose as their main residence the Hudson Valley mansion, Ferncliff, because she did not care for society life.

[3] Huntington remarried to Lytle Hull (1882–1958), a real estate broker and an old friend of Vincent Astor, on April 15, 1941.

The day of her death, the president of the New York Philharmonic, Carlos Moseley, opening the night at the Avery Fisher Hall, said that Helen Huntington Hull was "one of the great music lovers and benefactors of our time".

Even while married to Astor in 1914, they mostly led separate lives until their divorce, with Huntington preferring the company of her female friends.
