The Labour gains in Burnley mirrored voting across Lancashire.
Across the county, Labour won 39 seats on the county council, the Conservatives won 35, the Lib-Dems six, three independents and the Green Party got one seat.
The results mean that the council is hung with no single party having an overall majority on Lancashire County Council.
Labour made the biggest gains with 39 of the 84 seats – up 23 from four years ago.
The Conservatives had a bad day at the polls as they lost a total of 19 seats. Across the county, Liberal-Democrats also saw their number of councillors reduced to six.
Meanwhile, UKIP made in-roads by finishing second in four of the divisions.
In Pendle West, which covers parts of Reedley, Conservative Christian Wakeford secured the seat while Brierfield and Nelson North saw a Labour victory for Mohammed Iqbal.
Mr Phil Halsall, chief executive of the county council and returning officer for the election, said: “As no party has a clear majority, the main parties will need to consider the options for the future political governance of the council.
“These discussions will be taking place as a priority and an announcement will be made as soon as possible.” The council leader will be appointed on May 23rd.
