Arsenal de Sarandí is a sports club based in the Avellaneda Partido of Greater Buenos Aires, Argentina. In addition to football, the club hosts other sports such as field hockey, futsal, and handball.

Compared to other Argentinean clubs, Arsenal is a relatively young club, having been founded in 1957, by the former president of AFA, Julio Humberto Grondona. Arsenal reached the first division for the first time in 2002 and has won five titles in its history. Arsenal won its first Primera División championship in 2012, having previously won the Copa Sudamericana in 2007.

The club's colors are red and light blue, in honor of Avellaneda's traditional teams, Independiente and Racing. The club's nickname "El Viaducto" refers to the Avellaneda viaduct, a railway bridge over the Riachuelo River. It has become a symbol of the club and is featured prominently in its logo.

Jorge Burruchaga is the club's most famous former player, having started his career at Arsenal in 1979, and having served as a coach on several occasions. Burruchaga, or "Burru" as he is nicknamed, scored the winning goal for Argentina in the 1986 FIFA World Cup final against Germany.

The fans of Arsenal are known as "La Mafia". Although the club is relatively new and doesn't have a traditional clásico rival, it is believed that Club El Porvenir could be its closest one. Quite a few matches were played between the two clubs, due to the constant presence in different leagues of Argentine football.
