Holy Trinity Avonside was a heritage-listed Anglican church located in Linwood, Christchurch, New Zealand.

The church building was "damaged beyond the point of repair" in the February 2011 Christchurch earthquake and was demolished the following September.

[3] Architect Benjamin Mountfort, a parishioner, designed additions to the church including a bell tower and timber vestry in 1869.

Repairs were under way when the February 2011 Christchurch earthquake struck, when the church building suffered major damage including collapse of the chancel and most of the transepts.

Bishop Victoria Matthews defended the demolition, stating that her "priority has to be humans and the safety of the community.
