Which comet is called "Newton's Comet"?

C/1680 V1, also called the Great Comet of 1680, Kirch's Comet, and Newton's Comet, was the first comet discovered by telescope.

The comet was discovered by Gottfried Kirch, a German astronomer, on 14 November 1680 (New Style), in Coburg, and it became one of the brightest comets of the seventeenth century – reputedly visible even in daytime – and was noted for its spectacularly long tail.

While the Kirch Comet of 1680–1681 was discovered by—and subsequently named for—Gottfried Kirch, credit must also be given to Eusebio Kino, the Spanish Jesuit priest who charted the comet’s course. During his delayed departure for Mexico, Kino began his observations of the comet in Cádiz in late 1680.
