Raharney will be hoping for a repeat of last October's Championship final result.
Westmeath's six senior A hurling clubs are in action this weekend.
TEG Cusack Park plays host to all three games, with St. Oliver Plunkett's and Clonkill meeting in Mullingar on Saturday evening.
Clonkill, chasing a first championship title since 2020, were impressive winners over the defending county champions Raharney last time out.
While Oliver Plunkett's are looking for their first win of the season.
The action gets underway at 5.45pm
On Sunday, Castlepollard will be hoping to build on their win over Plunkett's last time out when they face Casteltown Geoghegan.
That game starts at 3.30pm.
The last game of the weekend sees Raharney meet Lough Lene Gaels in a replay of last year's county final.
