Perjury: The Hiss–Chambers Case is a 1978 book by Allen Weinstein on the Alger Hiss perjury case. The book, in which Weinstein argues that Alger Hiss was guilty, has been cited by many historians as the "most important" and the "most thorough and convincing" book on the Hiss–Chambers case. Weinstein drew upon 30,000 pages of FBI documents released through the Freedom of Information Act, the files of the Hiss defense attorneys, over 80 interviews with involved parties and six interviews with Hiss himself. In 1997, Weinstein published an updated and revised edition of Perjury, which incorporated recent evidence from Venona project decrypted cables, released documents from Soviet intelligence archives and information from former Soviet intelligence operatives.

Allen Weinstein was an American historian, educator, and federal official who served in several different offices. Under the Reagan administration, he was cofounder of the National Endowment for Democracy in 1983. He served as the Archivist of the United States from February 16, 2005, until his resignation on December 19, 2008. After his resignation, he returned to the International Foundation for Electoral Systems as a senior strategist and was a visiting faculty member at the University of Maryland.
