St. Peter's Woodlands Grammar School (commonly known as St Peter's Woodlands or SPW) is an independent Anglican co-educational early learning and primary day school located in the seaside suburb of Glenelg, South Australia, Australia.

The early learning centre offers playgroup, toddler and preschool programs for children from 2 years of age.

St Peter’s Woodlands is part of the Anglican Parish of Glenelg and, through its roots as the original Parish School, the school community is often involved in wider parish activities.

Upper Primary has more advanced roles, with leadership roles including School Captains, SSLC’S ( Student-Service-Leadership-council), House Captains and other various leadership roles.

The school was formed when St. Peter’s Glenelg and Woodlands Grammar combined in 1999.
