Two goals were enough to get the better of neighbours Roscommon.
Wesmeath have reached a first All-Ireland Intermediate Ladies Football Final since 2011.
Goals from Ciara Blundell and Karen Hegarty were the difference in a tight affair with Roscommon, 2-9 to 13 points the final score.
They now face a local derby against Meath in the decider in Croke Park on Sunday the 20th of December.
Midfielder Johanna Maher says there's great similarities in this team with the one nine years ago:
The government will allow full county panels to attend the remaining games in the All-Ireland championships.
Up to now - matchday panels have been restricted to no more than 26 players and 12 backroom team members.
Minister of State for Sport Jack Chambers has confirmed today that the government are relaxing these rules.
