Michael D. Horowitz (born December 11, 1938) is an American author and archivist in West Vancouver, British Columbia.[1][2]

His father, Sol Horowitz, and paternal grandparents were Russian Jews. Horowitz's American-born mother, Ethel (née Frankel), and his maternal side of the family were Romanian Jews.[3] Some of his relatives died during the Holocaust. He is the husband of author Cynthia Palmer, and the father of Winona Ryder and Uri Horowitz.[1]

A former close associate of Timothy Leary, he is responsible with his wife for the creation of the world's largest library of drug literature, the Fitz Hugh Ludlow Memorial Library.[4] He currently is the owner of Flashback Books, a mail-order bookselling operation, specializing in rare, scarce and out-of-print books, periodicals and related printed materials on the history, literature and science of psychoactive drugs.

Horowitz and actor Leonardo DiCaprio are planning a biopic about Leary to be written by Craig Lucas.[5]
