U.S. Ausonia Spezia
Unione Sportiva Ausonia Spezia was an Italian association football club located in La Spezia.
The club is notable because, over a dispute regarding the Campionato Alta Italia 1944, it was admitted to Serie B Alta Italia 1945–46 in place of Spezia F.B.C., the main club in the city.
However, the following season the dispute was settled, and Spezia was admitted to Serie B 1946–47 in place of Ausonia, that was relegated to Serie C 1946–47 by the FIGC. The club was immediately relegated to Promozione and later dissolved.
