Stadio Comunale Sant'Elia is a football stadium of Cagliari Calcio.

The stadium has a capacity of 23,486. It hosted three matches in the 1990 FIFA World Cup.

Its construction began in 1970, following Cagliari Calcio's first and so far only Scudetto, thus taking the place of the old Amsicora Stadium.

The stadium could accommodate up to about 60,000 spectators (the record attendance being approximately 70,000, was recorded against Saint Etienne). 

The stadium subsequently underwent major changes and restructuring for the 1990 FIFA World Cup. 

The maximum capacity of Sant'Elia was reduced to 39,905 spectators.

Before the 2002–03 season, also due to the reduced number of fans following the poor form of the team, long reduced to yo-yoing between Serie A and B, the stadium was restructured again. 

Over the athletics track, a new stand was built, behind the goals so as to reduce the distance between the terrace and the playing field, with the central terraces remaining intact. 

The new format of the stadium, which almost halved its maximum capacity to 23,486 seats, came under harsh criticism.
