The Malayan tiger (Panthera tigris malayensis, Malay: Harimau Belang), found in the southern and central parts of the Malay Peninsula[1], is a subspecies of tiger found in Thailand and Malaysia. Until 2004, it was not considered a subspecies in its own right. The new classification came about after a study by Luo S-J et al. from the Laboratory of Genomic Diversity, part of the U.S. National Cancer Institute.

Recent counts showed there are 600-800 Malayan tigers in the wild, making it the most common tiger subspecies other than the Bengal and perhaps also the Indochinese tigers. It is, nevertheless, still an endangered sub-species.
