Samuel Batchelder (8 June 1784 in Jaffrey, New Hampshire – 5 February 1879 in Cambridge, Massachusetts) was a United States inventor and author.

His family moved to New Ipswich when he was young, and by 1808 he was an investor in a cotton factory there, the second that was erected in New Hampshire.

In 1831, he was called on to undertake the erection of a cotton mill for the York Manufacturing Company in Saco, Maine, and to superintend its operations.

About 1832, he devised the first stop motion to the drawing frame, which afterward was used both in the United States and England.

In 1832 he patented the steam cylinders and connections which became universally used in dressing frames for drying yarns.
