A star party is a gathering of amateur astronomers for the purpose of observing objects and events in the sky. Local star parties may be one-night affairs, but larger events can last a week or longer and attract hundreds or even thousands of participants. Many astronomy clubs have monthly star parties during the warmer months. Large regional star parties are held annually and are an important part of the hobby of amateur astronomy. A naturally dark site away from light pollution is typical.

Participants bring telescopes and binoculars of all types and sizes and spend the nights observing astronomical objects such as planets, comets, stars, and deep-sky objects together. Astrophotography and CCD imaging are also very popular. At larger star parties, lectures, swap meets, exhibitions of home-built telescopes, contests, tours, raffles, and other similar activities are common. Commercial vendors selling a variety of astronomical equipment may also be present. As with other hobbyist gatherings, much camaraderie and discussion of various aspects of the hobby occurs at any star party.
