Charles R. Pellegrino (born 1953) is an American writer, the author of several books related to science and archaeology, including Return to Sodom and Gomorrah, Ghosts of the Titanic, Unearthing Atlantis, and Ghosts of Vesuvius. Pellegrino falsely claimed to have earned a PhD, and errors in his book The Last Train from Hiroshima (2010) prompted its publisher to withdraw it within a few months of publication.
