St. Brigid's Hospital (Irish: Ospidéal Naomh Bríd) was a psychiatric hospital in Ballinasloe, County Galway, Ireland.

The hospital, which was designed by William Murray, opened as the Connacht Asylum in 1833.

[1] After a redrawing of the asylum district boundaries in 1850, it was renamed the Ballinasloe District Asylum.

[2] As it expanded conditions became very overcrowded with nearly 1,200 patients by the early 1900s[1] and, having been renamed Ballinasloe Mental Hospital in the late 1920s, it accommodated some 2,000 patients by the 1950s.

After the introduction of deinstitutionalisation in the late 1980s[4][5] the hospital went into a period of decline and closed in 2013.
