Incidents in the Life of Madame Blavatsky: compiled from information supplied by her relatives and friends is a book originally published in 1886 in London; it was compiled by a member of the Theosophical Society, A. P. Sinnett, who was the first biographer of H. P. Blavatsky. Sinnett describes the many unusual incidents in Blavatsky's life beginning from her childhood in Russia, and asserts that Blavatsky had "an early connection with the supernatural world;" Sinnett also writes about Blavatksy's short, unlucky marriage and "decade of extensive global travels," about her period of learning in Tibet, and the "criticism she received about some of her 'phenomena' and practices."

Alfred Percy Sinnett was an English author and theosophist.
