The Portuguese Open was an annual tournament on men's golf's European Tour that was last played in 2010. It was first played in 1953, and was part of the European Tour's schedule beginning in 1973. Up until 2010, it was played in late March or early April each year, and was one of the first European Tour events of the season to be played in Europe, after the season spent the northern winter in Asia, Australasia and South Africa. In 2010, the tournament moved to a June date.
