Portugal's first representative was Pedro Madeira with the song "Deixa-me sentir", which finished in second-last place out of fifteen entries.

The country's current best result is a second place obtained by Victoria Nicole with the song "Esperança" at the 2024 edition, held in Madrid, Spain.

This achievement was then surpassed in 2022, when Portugal came 8th with Nicolas Alves and the song ‘Anos 70’, which was also the first entry sung entirely in Brazilian Portuguese dialect.

The following year, Portuguese-American singer Júlia Machado came 13th out of 16 with 75 points, achieving Portugal's third-best result in Junior Eurovision.

In 2015, the online broadcasts featured commentary in English by junioreurovision.tv editor Luke Fisher and 2011 Bulgarian Junior Eurovision Song Contest entrant Ivan Ivanov.
