Arlecdon is a village in the Borough of Copeland in Cumbria, England, near the town of Whitehaven.

St Michael's Parish church is an historic Grade II listed church, which is located about halfway between the villages of Arlecdon and Asby. The church founded in the 12th or 13th century. The church was restored in 1776 and its nave was rebuilt in 1829. The church was extensively remodelled, and had its tower added from 1903 to 1905. However, the church retains its chancel arch of c. 1630, which incorporates parts of the original 12th-century arch. The church's octagonal font is dated 1578. The church contains a stained glass window dedicated to Isaac Fletcher of Frizington. In 1904 the church was remodelled, with the addition of a bell tower and eight bells cast by John Taylor & Son of Loughborough.

In 2014 it was announced that the church is to close, and the bells hopefully re-used in another church.

The village also has a 19th-century primary school and an old Sunday school.

Arlecdon comes from the Old English 'earn-lāce denu', meaning 'eagle-stream valley'.
