The article deals with four original scripts for Munda languages invented in XX century by the native speakers of Munda languages. These are Ol Chiki invented by Raghunath Murmu for Santali language, Sorang Sompeng invented by Mangei Gomango for Sora, Warang Chiti invented by Lako Bodra for Ho and Bani Hisir invented by Rohidas Singh for Mundari. The invention of three of them corresponds religious traditions of Munda tribes, and two inventors (Gomango and Bodra) are also religious reformators. Scripts are of two types – Ol Chiki and Bani Hisir are alphabets, and two others are intermediates between alphabet and abugida. The author analyzes the structures of the lists of the signs. Some suggestions on the origin of the signs are made. In some cases the author proposes alternative versions of the origins of the Warang Chiti script, which was widely examined by H.J. Pinnow. Some signs of Sorang Sompeng may be compared with Roman and some Indian scripts, and Bani Hisir looks as if it is influenced by Ol Chiki and partly by the Warang Chiti system.
