The Pic du Midi de Bigorre or simply Pic du Midi (altitude 2,877 m (9,439 ft)) is a mountain in the French Pyrenees famous for its astronomical observatory, the Observatoire du Pic du Midi de Bigorre (Pic du Midi Observatory), part of the Observatoire Midi-Pyrénées (Midi-Pyrénées Observatory).
Construction of the observatory began in 1878 under the auspices of the Société Ramond, but by 1882 the society decided that the spiralling costs were beyond its relatively modest means, and yielded the observatory to the French state, which took it into its possession by a law of 7 August 1882. The 8 meter dome was completed in 1908, and housed a mechanical equatorial reflector. In 1946 Mr. Gentilli funded a dome and 60 cm, and in 1958 a spectrograph was installed. A 106-centimetre (42-inch) telescope was installed in 1963 funded by NASA, and was used to take detailed photographs of the surface of the Moon in preparation for the Apollo missions. A new 2 meter telescope, known as the Bernard Lyot Telescope was placed at the observatory in 1980 on top of 28 meter column built off to the side to avoid wind turbulence affecting the seeing of the other telescopes. It is the largest telescope in France. The observatory also has a coronograph, which is used to study the solar corona. A 60-centimetre telescope (the Gentilly's T60 telescope) is also implemented at the top of the Pic du Midi. Since 1982 this T60 is dedicated to amateur astronomy and managed by a group of amateurs, called association T60.

The observatory is located at , placing it very close to the Greenwich meridian. The observatory was featured in the video game under a different name. The observatory in-game is said to be located on the fictional Pic des Pyrenees.
