Harriet Newell Haskell (January 14, 1835 – May 6, 1907) was an American educator and school administrator from the U.S. state of Maine.

Her father was Bela B. Haskell, a banker and shipbuilder, and a citizen of Lincoln County, Maine.

He served two terms in the Maine Legislature and was collector of customs of his district under President Zachary Taylor.

The friend replied that there was only one such woman in the world, and that was Haskell, of Castleton College, but that she could not be removed from the State of Vermont.

Through Haskell's energetic efforts a temporary building was put up, and the school was reopened with 89 of the 130 young women who were in the institution when the fire came.

[2] The left side of Haskell's face was burned at Christmas time one year when her fake Santa Claus beard caught on fire; thereafter, she favored her right profile.

[6]A white marble Ruckstuhl statue of Haskell, a commissioned work by sculptor Hillis Arnold, was unveiled during the commencement exercises in June 1900, and placed in the Monticello library.

[10] While attending Mount Holyoke, Haskell made the acquaintance of Emily Gilmore Alden, and the two became constant companions and had a common home for 55 years.

The wall, 1,000 feet (300 m) in length, with an elaborate arch and gateway, was erected to the memory of Haskell by the alumnae of the institution.
