Acer pentaphyllum (五小叶槭 wu xiao ye qi) is a very rare, endangered maple species endemic to southwestern Sichuan in China, at altitudes of 2300–2900 meters.

Experts believe that survival is threatened by a combination of factors, including habitat loss, animal grazing, the harvest of woody fuel by local farmers, and fragmentation.

Several concerned individuals and organizations have been working to ensure this species is conserved and saved from extinction.

The UBC Botanic Garden established an ex situ conservation site at the UBC Botanic Garden for the conservation of this critically endangered Acer Pentaphyllum species.

CBCGDF filed a civil public interest environmental lawsuit against a hydropower company for potentially threatening the survival of the plant by building a new power station in southwest China.
