Edith Meiser (May 9, 1898 – September 26, 1993) was an American author and actress, who wrote mystery novels, stage plays, and numerous radio dramas. She is perhaps best known for bringing adaptations of Sherlock Holmes stories to radio in the 1930s. Meiser authored many radio scripts including Helen Hayes's first radio serial, The New Penny.

After forming a company and finding some success in radio, Mesier decided that Sherlock Holmes would make for a very good radio program but she was unable to interest NBC in a series unless she found herself a sponsor. It took more than a year for Meiser to interest a sponsor in the idea. George C. L. Washington, inventor of the first instant coffee, and also a Holmesian, agreed to sponsor the series which became The Adventures of Sherlock Holmes.

The premiere episode featured an adaptation of "The Adventure of the Speckled Band" on October 20, 1930, and starred William Gillette as Sherlock Holmes and Leigh Lovell as Dr Watson. Further episodes featured Richard Gordon in the role of Holmes until 1933 and Louis Hector from 1934 to 1935 with Richard Gordon again taking over for the last season in 1936.

All episodes were adapted or devised by Meiser and at the end of the first season a survey of American radio editors found that 94% said The Adventures of Sherlock Holmes was the best radio program.
