A battle cry is a yell or chant taken up in battle, usually by members of the same military unit. The content and nature of battle cries vary, depending on whether their intent is to threaten, invoke a family name or family lands, or call on a god for assistance. These cries can serve many purposes, including inspiring those otherwise inclined to stay back, terrifying the enemy, promoting a sense of esprit de corps, as well as communicating to allies that they have support.

Battle Cry is a 1955 film, starring Van Heflin, Aldo Ray and James Whitmore. The movie is based on the novel by Leon Uris, who also wrote the screenplay, and was produced and directed by Raoul Walsh. It received an Academy Award nomination for Scoring of a Dramatic or Comedy Picture.

Battle Cry was a popular grand strategic American Civil War board game produced by the Milton Bradley Company as part of their popular American Heritage series.
