Guilderland is a hamlet of the town of the same name in Albany County, New York, United States.

[2] In 1796, with hopes of establishing a manufacturing village, streets and lots were laid out and sold, and 54 houses built for the factory workers.

When the Great Western Turnpike was built through the hamlet in 1799 connecting Albany to the western frontier, Hamilton became the home to several taverns and other businesses catering to the pioneers.

[2] The glass works here folded in 1815, ending the hopes of this place becoming a major factory town.

[2][3] The Hamilton name continues to live on in the name of a Presbyterian church, the Hamilton Union Presbyterian Church that was founded in 1824.
