Henry Everett McNeil (25 September 1862 – 14 December 1929) was a leading children's author of the 1910s and 1920s, and was an original and core member of the Kalem Club circle around the writer H.P. Lovecraft. McNeil played a crucial role in the career of H.P. Lovecraft, in that he was the first to urge Lovecraft to submit his fiction to Weird Tales magazine in the early 1920s.
