The funding is seen as essential to manage the fallout from covid-19.
Westmeath County Council is proposing giving €30,000 each in support to Athlone and Mullingar Chamber.
Fianna Fáil's John Shaw says the advance funding is essential as chambers manage the fallout from the pandemic and help businesses recover.
The local authority has also approved 5,000 euro for the Athlone Gift Card scheme; 2,500 euro for the Moate is Open campaign; and 17,000 euro to create a single Mullingar Matters hashtag to promote the town.
