Will Radley is the youngest councillor in the Maldon district and could be one of the youngest in Essex.
The political science student joined Althorne Parish Council in March.
Will, 18, of Sunningdale Road, said there was some scepticism about his age from one or two members of the public, but overall he has received a warm welcome from councillors and villagers.
His first task will be helping to overhaul the council website so that it is updated and promotes the village, helping to boost tourism.
He is also concerned about any potential mass development in Althorne.
