The USA’s first space station, Skylab, was launched into Earth’s orbit.
Skylab was launched atop a modified Saturn V rocket, with the launch itself commonly referred to as Skylab 1. Both the launch and deployment of Skylab were a little bit of a disaster, with multiple parts of the station sustaining damage. Nevertheless, Skylab saw three astronaut crews live aboard it between 1973 and 1979 when it was de-orbited.
