Council elections for the City of Preston, Lancashire were held on 6 May 2010. They coincided with the United Kingdom general election, 2010 and the other United Kingdom local elections, 2010. Nineteen electoral wards were fought with those councillors elected in the corresponding elections in 2006 defending their seats due to the "in thirds" system employed in Preston local elections.
The previous elections to Preston council occurred in 2008 but due to the "in thirds" system employed by Preston council, councillors are elected for four-year terms. This means gains, losses, and vote share comparisons this year are with those fought in 2006.
