Daniel Wadsworth (August 3, 1771 – July 28, 1848) of Hartford, Connecticut, was an American amateur artist and architect, arts patron and traveler.

[3] Young Daniel was educated partly at home; he was introduced to the great art and architecture of the royal courts of Europe by his father, who traveled there with him (see Grand tour).

He took many trips with writer Benjamin Silliman and Trumbull to Niagara Falls and the White Mountains (New Hampshire) to write accounts and sketch the landscapes they saw.

He played a formative role in the life and work of a fellow son of Hartford, Frederic Edwin Church, whose prodigious talent Wadsworth was among the first to recognize.

He then announced his plans to build "a Gallery of Fine Arts" on Main Street in Hartford, which would later be named after him as the Wadsworth Atheneum.
