Cadley is a largely residential suburban area of Preston, Lancashire, England, and an electoral ward. The population of the ward taken at the 2011 census was 4,589. It is usually considered to be a district of the larger suburb of Fulwood (and formed part of the pre-1974 Fulwood Urban District), but was historically separate as evidenced, for instance, in the name of Fulwood and Cadley County Primary School.
