Teams
Overview
All but one of the twelve teams from the 2012 championship participated in the top tier of Offaly hurling in 2013.
Lusmagh, who defeated St Rynagh's by 4–11 to 2–14 in the final of the intermediate championship in 2012, availed of their right to automatic promotion to the senior championship.
Similarly, Drumc defeated Shamrocks in the 2012 relegation play-off, and so Shamrocks were relegated to the intermediate grade for 2013.
