Wellington Square, Perth, Public park in Perth, Australia.

Wellington Square in Perth is a large green space with landscaped gardens, walking paths, and modern playground equipment for children of various ages. The park spans several blocks and connects different areas through its network of pathways.

The park began as a swamp drained in the 1830s and was used to exercise horses, known as the Recreation Ground or the Rec. In 1898 it was cleared for cricket fields and named after the Duke of Wellington, British prime minister at the time of the Swan River Colony's settlement. Before the WACA Ground was built in the 1890s, it served as Perth's main cricket ground. A A$18.7 million redevelopment opened in March 2021, and the City of Perth dual-named it Moort-ak Waadiny / Wellington Square on 14 October 2021.

The name Moort-ak Waadiny was added alongside Wellington Square in October 2021, a Noongar dual name approved by Landgate. The 2021 redevelopment created a place of reflection commemorating the Stolen Generation. The square also serves as a live music venue and a meeting place for local schools and clubs.

The park sits on Wellington Street in East Perth, and its 2020–2021 redevelopment added new paths and facilities, including a playground and basketball courts. The square is used by local schools and clubs for cricket and athletics, so some areas may be busy at those times.

The park's dual name, Moort-ak Waadiny / Wellington Square, was approved by Landgate on 14 October 2021, after the City of Perth proposed it. The Noongar name sits alongside the colonial one on signage, and the 2020-21 redevelopment added a place of reflection commemorating the Stolen Generation.
