All Hallows Staining was a Church of England church located at the junction of Mark Lane and Dunster Court in the north-eastern corner of Langbourn ward in the City of London, England, close to Fenchurch Street railway station. All that remains of the church is the tower, built around 1320 AD as part of the second church on the site. Use of the grounds around the church is the subject of the Allhallows Staining Church Act 2010.
The first mention of the church was in the late 12th century. It was named "Staining", which means stone, to distinguish it from the other churches of All Hallows in the City of London, which were wooden.
The old church survived the Great Fire of London in 1666 but collapsed five years later in 1671. It was thought its foundations had been weakened by too many burials in the churchyard close to the church walls. The church was rebuilt in 1674.
The parishes of All Hallows Staining and nearby St Olave Hart Street were combined in 1870. At that time All Hallows Staining was demolished, leaving only the tower.
