Thomas Y. Howe, Jr. (1801 – July 15, 1860) was a U.S. Representative from New York.
Born in Auburn, New York, Howe completed preparatory studies, studied law, was admitted to the bar, and practiced in Auburn.
Howe was also involved in several businesses, including: treasurer and a member of the board of directors for the Auburn and Syracuse Railroad; president of the Lake Ontario, Auburn and New York Railroad; editor of the Cayuga New Era newspaper; and trustee of the Auburn Savings Bank.
A Democrat, Howe served on the board of inspectors for the Auburn State Prison from 1834 to 1838. He was elected Surrogate Judge of Cayuga County, and served from March 18, 1836 to April 14, 1840.
Howe was elected to represent New York's 25th District in the Thirty-second Congress, and he served from March 4, 1851 to March 3, 1853. He did not run for reelection, but ran instead for Mayor of Auburn. He was elected and served a one-year term, March 1853 to March 1854.
Howe died in Auburn on July 15, 1860, and was buried at Fort Hill Cemetery in Auburn. Howe was one of the donors of the land for the cemetery, had been an incorporator of the Fort Hill Cemetery Association, and served as secretary of the association's first board of trustees.
His last name is sometimes spelled "How," which is how it appears on his gravestone.
