Couple's Retreat Garden, Classical garden in Pingjiang Street, Suzhou, China.

Couple's Retreat Garden is a 0.33 ha classical garden in Suzhou split by its central residential hall into an east and west garden, an unusual layout for a Suzhou garden. The east garden, the larger of the two, holds a pond and rock grotto ringed by a covered walkway linking its buildings, with a small fruit orchard attached. The west garden groups several structures around a small grotto and a library annex, joined to the residence. Water surrounds the site on three sides.

Lu Jin, prefect of Baoning, built the original garden in 1874 under the name She Yuan, taken from Tao Yuanming's line "daily strolling in the garden for pleasure". Shen Bingcheng, magistrate of Susong, bought it and rebuilt it in its present form, renaming it Couple's Retreat Garden. It joined the UNESCO World Heritage list of Suzhou classical gardens in 2000 and became a national protected site in 2001.

The garden reflects traditional Chinese design principles where water, rocks, and plants are carefully positioned to create balance and harmony. Visitors can experience this thoughtful arrangement as they walk through different areas and observe how each element relates to the others.

The garden is accessible on foot through several entrances, with the main gate on Pingjiang Street open during daylight hours. The pathways throughout are manageable for most visitors, with connections between different areas clearly marked.

The garden's name, Ou Yuan, plays on ou, meaning "pair": it refers both to the married couple Shen Bingcheng and his wife and to the layout, where east and west gardens mirror each other around the central residence. The east garden's yellow-stone rockery survives from the earlier She Garden.
