The Toulouse Observatory (French: Observatoire de Toulouse) is located in Toulouse, France and was established in 1733.

It was founded by l'Académie des Sciences, Inscriptions et Belles-Lettres de Toulouse ("Academy of Science, Inscriptions and the Humanities of Toulouse"). It was moved 1841 and again in 1981.^{[citation needed]}

In 1987, Genevieve Soucail of the Toulouse Observatory and her collaborators presented data of a blue ring-like structure in Abell 370 and proposed a gravitational lensing interpretation

In the 1990s the observatory worked on MEGACAM with several other institutions.

The observatory was started by Garipuy in the 1730s with support from the Academy of Sciences.

Félix Tisserand was a famous director from 1873 to 1878. He published Recueil d'exercices sur le calcul infinitesimal as well as making several expeditions, including an 1874 trip to Japan. Henri Joseph Anastase Perrotin was Tisserand's assistant astronomer, and they both went to the Paris Observatory in 1878. Tisserand was succeeded by Benjamin Baillaud.

The observatory was originally founded in 1733. Launch instruments at the observatory included two refractors and 28 inch quadrant, and one clock. By 1840 and additional clock by Julien le Roi of Paris was added.

Among the early observations at the observatory were the 1736 and 1743 transits of Mercury. These observations were conducted by Garipuy, who also observed the transit of Mercury in 1753. Garipuy also built and observatory in his house and conducted observations from there.
