Daniel Chadwick (January 5, 1825 – November 23, 1884) was an American politician.

Two years later his father's death recalled him to Lyme, where he continued the practice of his profession.

He served as a member of the Connecticut State Senate in 1858, and of the Connecticut House of Representatives in 1859, and again as a member of the State Senate in 1864, being thus twice ex officio a fellow of Yale College.

He died very suddenly at his home in Lyme, November 23, 1884, in his 60th year.
