The Galileo House is an 11-story building in Grand Theft Auto V and Grand Theft Auto Online. It is located at the intersection of Spanish Avenue and Meteor Street in Hawick, Los Santos. The companies Isomorph Technologies, Queefstat, Flojoscope, Miasma and Thermoskite have offices in this building. It cannot be entered and plays no role in the storyline.
- One of the 15 knife flights is performed between this building and the adjacent Vinewood Gardens Hotel.
- The building is most likely named after the Galileo Observatory and Galileo Galilei, a 16th-century Italian physicist and astronomer.
- During the day, part of the adjoining Vinewood Gardens Hotel sign can be seen on the left side of the 4th floor of the building, only from a certain distance and through the scope of a sniper rifle.
