James Herbert Lorrain, or Pu Buanga, (6 February 1870 – 1 July 1944) was a Scottish Baptist missionary in northeast India, including Mizoram, Assam, and Arunachal Pradesh. He and Frederick William Savidge reduced the Lushai language (a Colonial British name, present Mizo language) to writing—devised an alphabet using Roman lettering and phonetic form of spelling based on Hunterian system translation; compiled grammar and dictionaries for missionary activities and clerical administration.
