The Ellis (NCC-1701/7) was a Class F shuttlecraft which was assigned to the USS Enterprise in the 2260s.

In 2268, the Ellis was used to transport Captain James T. Kirk and a landing party to the surface of a Class M planet in the Omicron Persei system. (TOS comic: "Cura Te Ipsum")

Interestingly, the Ellis's registry number was assigned to the various incarnations of the shuttlecraft Galileo.
