2011–12 Pro12

The 2011–12 Pro12 League (also known as the RaboDirect Pro12 for sponsorship reasons) was the 11th season of the rugby union competition originally known as the Celtic League, the second with its current 12-team format, and also the first with RaboDirect as title sponsor.

The twelve teams competing were the four Irish provinces, Munster, Leinster, Connacht and Ulster; two Scottish regions, Edinburgh Rugby and Glasgow Warriors; four Welsh regions, Cardiff Blues, Newport Gwent Dragons, Ospreys and Scarlets; and two Italian clubs Aironi and Benetton Treviso.

The competition was won by Ospreys, who defeated Leinster in the final 31–30.
