Drumchapel-based We Step Together (WST) won the Queen's Award for Voluntary Service for its work in tackling isolation, loneliness and exclusion over the past 17 years.
The group - which has around 50 members who range in age from their 20s to 64 from across Glasgow -has also been working with school pupils to raise awareness of learning disability issues.
Next month they will attend a civic reception with Lord Provost Sadie Docherty at the City Chambers where they will be presented with a trophy.
Donald Hewitson, who has worked with the group for seven years, said he was "so proud" of the members.
He said: "The group has worked so hard over the years to apply for funding and get to where they are today. I'm so proud of them - what they've achieved is the equivalent of an individual MBE."
Earlier this month some of the members attended Her Majesty's Garden Party at the Palace of Holyroodhouse in Edinburgh.
Donald said: "That was fantastic but not everyone could come. So we are really looking forward to the civic reception."
The group has also worked with different groups in the West End, including youth club DRC Generations and the Yoker Resource Centre.
