Consumer group CAMRA is urging Prime Minister David Cameron to appoint a new minister for pubs.
In a letter to Cameron, the group suggests that Lib Dem Greg Mulholland or Tory Nigel Evans could replace John Healey, who was appointed to the post towards the end of Labour's regime.
Mike Benner, CAMRA chief executive, said: "It is a positive sign that the new Prime Minister chose to enjoy a pint in his local community pub on election night.
"CAMRA hopes that the new government will include a minister for pubs tasked with safeguarding the future of the nation's pubs."
He added: "A dedicated minister for pubs is vital to ensure that the fate of community pubs does not fall through the gaps between these government departments.
"CAMRA will be asking its 110,000 members to contact the Prime Minister to support the reappointment of a minister for pubs."
Campaign groups Fair Pint and Justice for Licensees have also backed calls for a new pubs minister.
