Labour is no longer the largest party on Oxford City Council, which has remained in no overall control.
The Green party now has eight councillors on the city council
The party lost four of its seats, leaving it with just 17, while the Lib Dems took two wards to rise to 19.
One of Labour's lost seats went to an Independent Working Class Association candidate in Northfield Brook ward.
Labour also lost three seats on Cherwell District council, which remained in Tory hands alongside West Oxfordshire District Council.
The Conservatives gained four more seats on West Oxfordshire council - two apiece from the Liberal Democrats and from independent parties.
Lib Dem leader Sir Menzies Campbell said of his party's success in Oxford: "[The Lib Dems'] hard work and dedication has been rewarded by the voters.
"We will continue to fight for local residents and work towards a safer, fairer, and greener Oxford."
The Green party now has eight councillors on the city council while the Independent Working Class Association's victory takes its tally to four. The Tories remain without a seat.
