St. Mary's Church, Walthamstow, is a Church of England parish church in Walthamstow Village, a conservation area in Walthamstow, east London. It was founded in the 12th century. It retains over one hundred and fifty brasses and monuments, the oldest dating from 1436, though all that now remains of the original Norman church is some pillar bases and the chisel marks on them.
St Mary's is an active church today, with a large congregation involved in supporting the local community. In recent years the church has improved the facilities that support its community support work. There have also been projects to maintain the ancient fabric of the church building. This has included renovation of the churches ten bells, most of which were cast at the nearby Whitechapel Bell Foundry. The work on the bells, which are regularly rung, will allow them to peal for at least another hundred years.
