The Batman Family or Bat Family for short is a network of likeminded crimefighters who operate in and around Gotham, with Batman as its head.

The group usually are seen interacting with one another and assisting in each other's cases in their respective series. When a new vigilante emerges in the city Batman deduces their identity relatively quickly. Although some members occasionally resent Batman’s intrusion into their lives, all respect him as a legend within the superhero community and rarely challenge his authority.

Most of the members also have a strong rapport with the Dark Knight due to their long and close relationships with him over the years, and consider him a close friend as well as ally.

In a 2002 storyline in which Bruce Wayne, Batman’s secret identity, is accused of murder, Batman's friends gather to prove his innocence. It has also been implied through Batman's history that this network serves as a surrogate family for Batman and keeps him from slipping too far into his ruthless vigilante persona.

A collective of fictional characters appear in American comic books published by DC Comics featuring the superhero Batman as the main protagonist.

Since Batman's introduction in 1939, the character has accumulated a number of recognizable supporting characters. The first Batman supporting character was Commissioner James Gordon, who first appeared in the same comic book as Batman in Detective Comics #27 (May 1939), and is Batman's ally in the Gotham City Police Department. Robin, Batman's vigilante partner, was introduced in the Spring of 1940, Alfred Pennyworth, Batman's butler, was introduced in 1943, and Barbara Gordon was introduced in 1967.

The "Batman family", or "Bat-Family", is the informal term for Batman's closest allies, generally masked vigilantes operating in Gotham City. Batman also forms strong bonds or close working relationships with other superheroes, including Justice League members Superman, Green Arrow, Zatanna and Wonder Woman as well as members of the Outsiders superhero team. Others such as Jason Bard, Harold, Onyx, and Toyman work for him.

In addition, Batman has perhaps the most well known collection of adversaries in fiction, commonly referred to as Batman's rogues gallery, which includes the Joker, Penguin, Riddler, and Two-Face, among others. He also has several love interests, including Catwoman, Talia al Ghul, Silver St. Cloud, Poison Ivy, and Julie Madison.
