The Société Astronomique de Tunisie (SAT) is an astronomy association dedicated to sharing knowledge and encouraging interest in the sky and space sciences. Its work spans celestial calculations, observing campaigns, astronomical instrumentation, and the history and popularization of astronomy. The society organizes activities and publishes educational information for astronomy enthusiasts, including monthly sky-event calendars calculated for Tunisia and updates on notable phenomena such as eclipses.

Its specialist commissions cover ephemerides and celestial mechanics, lunar-crescent visibility, solar physics, variable stars, and astronomy outreach. SAT also features astrophotography and observations of the Sun, Moon, Milky Way, planets, comets, nebulae, star clusters, galaxies, quasars, and supernovae. Through its events calendar, press releases, publications, and public-facing astronomy resources, the organization helps people follow astronomical developments and learn how they can be observed.
