Werewolf by Night (birth name Jacob Russoff, legal name Jacob Russell, nicknamed Jack) is a fictional character, an antiheroic werewolf appearing in American comic books published by Marvel Comics. The Werewolf by Night (usually referred to by other characters simply as the Werewolf) first appeared in Marvel Spotlight #2.

The Werewolf by Night character first appeared in Marvel Spotlight #2 (Feb. 1972) and was based on an idea by Roy Thomas. The series name was suggested by Stan Lee and the debut story was crafted by Gerry Conway and Mike Ploog. The character made additional appearances in Marvel Spotlight #3 and #4 and then graduated to his own eponymous series in September 1972.Werewolf by Night was published for 43 issues and ran through March 1977. Issue #32 (August 1975) contains the first appearance of Moon Knight. Jack Russell co-starred with Tigra in Giant Size Creatures #1 (July 1974), which was the first appearance of Greer Grant as Tigra instead of the Cat. That series was retitled Giant-Size Werewolf with its second issue.

Jack Russell was dormant for most of the 1980s. The character's appearance was radically revamped in Moon Knight #29 (March 1983). He guest-starred in various issues of Spider-Woman, West Coast Avengers, and Doctor Strange: Sorcerer Supreme.

Werewolf by Night was later revived in the pages of Marvel Comics Presents, where he appeared irregularly from 1991-1993. He made regular appearances as a supporting cast member in the pages of Morbius, the Living Vampire from 1993-1995. A letters page in an issue of Morbius mentioned that a Werewolf by Night miniseries by Len Kaminski and James Fry was in the works, but the miniseries was never published.
