The council and Gloucestershire Constabulary will be issuing offenders with tickets after taxi drivers said they could not get to their rank.
A spokesman from the authority said the crackdown would help taxis collect revellers leaving clubs in Eastgate Street.
He said there was no reason to park illegally as there were three car parks nearby that were free after 1600 BST.
Ch Insp Rich Burge, of Gloucestershire police, said: “At the moment we are finding that Eastgate Street is full of parked vehicles the entire length of the road on both sides on Friday and Saturday nights.
“This is not acceptable because it means the street is becoming congested and at times dangerous.
“I would make a direct appeal to those driving into the city to use the free parking that is available and not to be tempted to take spaces they shouldn’t.”
