The etymology of the name Malang is uncertain. One of the theories said that the name Malang is derived from the words Malangkuçeçwara, which means "God has destroyed the false and enforced the right". The words were taken from an ancient term which mentions a legendary temple called Malangkuçeçwara, supposedly located near the city Malang. The word Malangkuçeçwara was applied as the motto of the city of Malang. The name "Malang" first appeared on the Pamotoh / Ukirnegara Inscription (1120 Saka / 1198 AD) which was discovered on 11 January 1975 by a Bantaran plantation administrator in Wlingi, Blitar Regency. In the copper inscription, one part is written (with the following translation) as follows.
