Private Parts is the first book by American radio personality Howard Stern. It was released on October 7, 1993 by Simon & Schuster and edited by Larry "Ratso" Sloman and Judith Regan. By mid-1992, Stern's radio show The Howard Stern Show had become the number one morning program in New York City and had hosted the Saturday night television show The Howard Stern Show on WWOR-TV, since 1990. After development on a feature film for New Line Cinema fell through, Stern secured a deal with Simon & Schuster in early 1993 to write a book.

Private Parts was an instant commercial success upon release. It debuted at number one on The New York Times Best Seller list and remained there for five weeks. After five days, it became the fastest selling title in Simon & Schuster's history. A paperback edition with extra material was released in 1994. The autobiographical chapters of the book were adapted into the 1997 feature film Private Parts, which starred Stern and his radio show staff playing themselves. This release was supported with a second paperback print of the book.
