The Ulu scripts, locally known as Surat Ulu ('upstream script') are a family of writing systems found in central and south Sumatra, in the regions of Kerinci, Bengkulu, Palembang and Lampung, Indonesia. They were used to write manuscripts in Sumatran languages and Malay. The Malay writing was gradually replaced by the Jawi script, a localized version of the Arabic script.
