Portugal has entered the Eurovision Song Contest 46 times since its debut in the 1964 contest. Portugal has missed only three contests since the country's debut in 1964.
Portugal has been absent from four contests since their first participation. The country's first absence was in 1970 where Portugal, along with four other countries, boycotted the contest due to the result of the previous year, when four countries were announced the winner.
Portugal missed the 2000 contest due to their poor average results over the past five years. Despite being eligible to enter the 2002 contest, RTP declined to enter, and was replaced by eventual winner Latvia.
On 22 November 2012, Portugal confirmed that they would not be participating in the upcoming contest in 2013.
