St Martin Pomeroy was a parish church in the Cheap ward of the City of London.
The church stood on the east side of Ironmonger Lane in the Cheap ward of the City of London. John Stow suggested that the name "Pomary" indicated that apple trees had once grown near the church. The patronage of the church belonged to the prior and canons of St Bartholomew the Great, until the dissolution of the priory, when it passed to the Crown.
In 1627 much of the north wall had to be rebuilt, and two years later the whole church was "repaired and beautified" at the cost of the parishioners. The church was destroyed in the Great Fire of London in 1666 and not rebuilt. Instead the parish was united with that of St Olave Jewry and the site of the church retained as a burial ground.
