Shamus is a masculine given name with Irish origins, derived from the name Séamus, which means 'supplanter.' The name has been used in Ireland and has gained popularity in other English-speaking countries, particularly in the United States. Initially considered a misspelling of Séamus, Shamus became more prominent after the Great Irish Famine when Irish migrants were employed in public services. Today, it is often associated with detectives and police officers due to its historical use in these professions. The name has also appeared in various forms of media, including films and video games.
