Withdrew from championship
The draw for the Ulster championship was seeded, and took place in a single elimination format. Antrim received a bye to the final, down to the semi-final.
There was no entry from the Ulster Championship to the 2012 All-Ireland Senior Hurling Championship proper. Antrim instead entered that competition through the preliminary round of the Leinster Senior Hurling Championship.
The other Ulster teams were not eligible, and took part in the 2012 Christy Ring Cup, the second tier All-Ireland hurling championship. Unlike in 2011, only four teams entered the competition this year.
