Jacob Sloat Fassett (November 13, 1853 – April 21, 1924) was a businessman, lawyer, and member of the United States House of Representatives from New York.

He studied law at his father's firm, Smith, Robertson & Fassett, was admitted to the bar in 1878 and commenced practice in Elmira.

He died on April 21, 1924, in Vancouver, British Columbia, Canada, while returning from a business trip to Japan and the Philippines.

In World War II, the United States liberty ship SS Jacob Sloat Fassett was named in his honor.

It was here on the 28 acres (110,000 m2) of Greycourt at the end of Little Island Road in Falmouth, Massachusetts, where Jacob and his wife Jennie Crocker Fassett built a large summer estate in 1916 - 1918.

Faculty members of the art department have their offices in Fassett Commons, which is listed on the National Register of Historic Places.

Although Jacob Sloat Fassett and Jennie Crocker had several children (one of whom was a doctor), none of them went into politics like their father.

[5] Jacob Sloat Fassett, III lived his remaining years on what was left of the estate in West Falmouth.
