V. is the debut novel of Thomas Pynchon published in 1963, concerning the journey of Benny Profane through a Decadent group of artists in the late 1950s, along with the attempt of an aging traveller named Herbert Stencil to locate the mysterious woman he knows only as V. Considered to be a masterpiece, and one of the most important (and first) post-modern books.

V. is considered by some to be the first book of a Pynchon "trilogy", based primarily on the occurrence of the letter "v" in the title. Books two and three are Vineland and Gravity's Rainbow.
