Malus sikkimensis is a rare species of apple known by the common name Sikkim crabapple. Its Chinese name is xi jin hai tang (锡金海棠).

It bears white and pink flowers and dark red fruit. It was first published in Gatt. Pomac. in 1890.

It is native to China, Nepal, Bhutan, Assam, Tibet and parts of India, where it is threatened due to loss of habitat.{{cite web |last1=Rhodes |first1=L. |last2=Maxted |first2=N. |date=2016 |title=Malus sikkimensis. e.T50050877A50671549. |url=https://www.iucnredlist.org/species/50050877/50671549 |access-date=29 October 2023 |website=The IUCN Red List of Threatened Species 2016 |quote=Last assessed 01 July 2014}}

The edible fruits are a primary source (within India and the Himalayas) of dietary dihydrochalcones and flavonoids (both organic compounds). An extract of the fruit has potential for protective and therapeutic properties.{{cite web |last1=Shri |first1=K.S. |last2=Sharma |first2=Y.P. |last3=Pankaj |first3=S. |last4=Pratima |first4=V. |last5=Randhawa |first5=S.S. |date=2018 |title=Wild edible fruits of Himachal Pradesh state centre on climate change & UNEP-GEF-MoEFCC project report. |url=https://hpbiodiversity.gov.in/Pdf/Wild%20Edible%20Fruits%20of%20Himachal%20Pradesh.pdf. |access-date=10 September 2021}}
