Melodi Grand Prix is an annual music competition organised by Norwegian public broadcaster Norsk Rikskringkasting. It determines the country's representative for the Eurovision Song Contest, and has been staged almost every year since 1960. The festival has produced three Eurovision winners and nine top-five placings for Norway at the contest. However, Norway holds the record for the number of entries who have come last since entering Eurovision; 11 in all. Despite this, the competition still makes considerable impact on music charts in Norway, and in other Nordic countries, with the 2008 winner topping the Norwegian charts.

Dansk Melodi Grand Prix is an annual music competition organised by Danish public broadcaster Danmarks Radio, which determines the country's representative for the Eurovision Song Contest. The festival has produced three Eurovision winners and thirteen top-five placings.

Melodi Grand Prix Junior is the Norwegian national final that selects the entry to represent Norway in the annual Melodi Grand Prix Nordic junior singing competition. Between 2003 and 2005, Norway sent its winners to the Junior Eurovision Song Contest, when MPG Nordic wasn't active. In 2006 Norway withdrew itself from JESC, along with Denmark and Sweden, to participate in Melodi Grand Prix Nordic instead. From 2010 Melodi Grand Prix Junior has ended with the national final.

The Junior Eurovision Song Contest, often shortened to JESC, Junior Eurovision or Junior EuroSong, is a song competition which has been organised by the European Broadcasting Union (EBU) annually since 2003 and is open exclusively to broadcasters that are members of the EBU. It is held in a different European city each year, however the same city can host the contest more than once.
