Grantham Alive Church is a Christian church located in the town of Grantham, Lincolnshire, England. It was originally built in 1870 as the St Peters Hill Congregational Church, and later became the United Reformed Church. It was sold in 2011 to the Alive Church.
The church is a Grade II listed building, and is built in the Gothic Revival style. It is made of red brick with stone dressings. The church has a nave, chancel, and bell tower.
The interior of the church is decorated with stained glass windows, many of which were designed by Charles Eamer Kempe. The church also has a number of memorials to local people, including a war memorial to those who died in World War I.
The church is now used by the Alive Church, which is a non-denominational church.
