Milltown Cemetery (Irish: Reilig Bhaile an Mhuilinn) is a large cemetery in west Belfast, Northern Ireland.
It lies within the townland of Ballymurphy, between Falls Road and the M1 motorway. Milltown Cemetery opened in 1869 and there are now approximately 200,000 of Belfast's citizens buried there. Most of those buried there are Irish Catholic. Within the cemetery there are three large sections of open space, each about the size of a football field, designated as "poor ground". Over 80,000 people are buried in the cemetery's poor grounds, many of whom died in the flu pandemic of 1919. Since 2007, the 55-acre (220,000 m2) cemetery has undergone extensive work, reversing years of neglect.
