Niall James Horan ( NY-əl HOR-ən; born 13 September 1993) is an Irish singer-songwriter.

He rose to prominence as a member of the boy band One Direction, formed in 2010 on the singing competition The X Factor. The group released five albums and went on to become one of the best-selling boy bands of all time.

After the band declared a hiatus in 2016, Horan signed a recording deal as a solo artist with Capitol Records. He has since released three albums: Flicker (2017), Heartbreak Weather (2020), and The Show (2023). Flicker debuted at No. 1 in Ireland and the US, and reached the top three in Australia and the UK. The album's first two singles, "This Town" and "Slow Hands", reached the top 20 in several countries. Heartbreak Weather was released in March 2020, and debuted at No. 1 in the UK, Ireland and Mexico, and at No. 4 in the US.

Horan released his third studio album, The Show, in June 2023, after dropping the singles "Heaven" in February and "Meltdown" in April.
