Castledare Boys' Home was a residential college in Wilson, Western Australia owned and operated by the Congregation of Christian Brothers from March 1929 to 1983 and established for the treatment and training of intellectually handicapped children.

Later it had a more general educational and residential focus, accommodating boys from various backgrounds, including child migrants, wards of the state, and orphans.

The site was previously a pastoral property called "Niana" built by the Fleming family between 1906 and 1908, and when taken over occupied 34 hectares (83 acres).

The Mother of Perpetual Succour Chapel was constructed in 1957 and blessed and opened by Archbishop Redmond Prendiville.

In 1994, the Parliament of Western Australia was presented a petition with 30,000 signatures demanding an inquiry into the sexual and physical assault that took place in various institutions run by the Christian Brothers, including Castledare.
