The Coast Open, or Abierto del Litoral, is a golf tournament played in Argentina.

Founded in 1932 as the Torneo de Profesionales (Professional Tournament), a name only used for the first two editions, it has always been played at the Rosario Golf Club in Rosario, Santa Fe.

The tournament has been a fixture on the PGA Tour Latinoamérica Developmental Series.

It was also included on the European Challenge Tour schedule in 2007 (2008 season), being one of five tournaments held in Latin America, and four in Argentina, that season.

In 1932, 1952 and 1983 the championship ended in a tie, with no playoff being held to determine an outright winner.
