Aldosivi Mar del Plata is a prominent football club from Mar del Plata, currently competing in the Argentine Division 1, the top flight of Argentine football. Known as "El Tiburón" (The Shark), Aldosivi plays in distinctive blue and yellow vertical stripes at the Estadio José María Minella. The club was founded in 1913 by workers of the Mar del Plata port, with its name derived from the first letters of the founding members' surnames. For much of its history, Aldosivi was a classic yo-yo club between the second and third divisions. Their key era arrived in the 21st century, culminating in a historic first promotion to the Primera División in 2018 under coach Martín Palermo. They cemented their top-flight status with a remarkable sixth-place finish in 2019 and a subsequent Copa de la Superliga campaign. The modern era sees Aldosivi as an established Primera side, known for a gritty, hard-working style that makes them a difficult opponent for any team. Their fan base, the "Hinchada del Tiburón," is known for its passionate and vocal support, turning the Minella into a daunting venue. Aldosivi's story is one of perseverance and pride, a true testament to a club's journey to the summit.
