St Martin Orgar was a church in the City of London in Martin Lane, off Cannon Street. Its name is said to derive from one Ordgarus (Odgarus, Orgarus, Ordgar, Orgar), a Dane who donated the church to the canons of St Paul’s. It is sometimes considered being one of the churches mentioned in the nursery rhyme "Oranges and Lemons". Most of the building was destroyed in the Great Fire of London in 1666, but the tower and part of the nave were left standing. The parish was merged with St Clement Eastcheap. The churchyard remained in use by the combined parish until 1853. *
