Ralph Wedgwood (1766–1837) was an English inventor and member of the Wedgwood family of potters. His most notable invention was the earliest form of carbon paper, a method of creating duplicate paper documents, which he called "stylographic writer" or Noctograph. He obtained a patent for the invention in 1806. Ralph was the cousin and business partner of Josiah Wedgwood. Funding for Ralph's inventions were provided by Josiah's eldest son, Josiah Wedgwood II.
