Brian Nicholas McFadden (born 12 April 1980 in Artane, Dublin, Ireland) is an Irish singer.

McFadden came to fame as a member of the boy band Westlife. He left the band on 9 March 2004 to work on solo projects. (McFadden performed with Westlife as Bryan McFadden but afterwards decided to use the original spelling of his name "Brian".)

McFadden married Kerry Katona in 2002. The couple have two children, Molly and Lilly Sue, but they announced their separation in September 2004.

He released his debut single "Real to Me" in September 2004, and it went to No. 1 on the UK charts. His second single, "Irish Son", was released in November 2004 and went to No. 6 on the UK charts. However, the album Irish Son only reached the top 30 in the UK charts, while the third single from the album, "Demons", only reached #28 in May 2005.

The video for "Irish Son" caused some serious controversy, as it showed a Christian Brothers school in Sutton whilst the lyrics implied that McFadden had been physically abused at a CBS school, when he did not actually attend one. The song for the most part criticises the alleged negative hold that the Catholic Church held on Irish society in the past, while McFadden claims in the song that "it was leaving that saved me".

Since then, Brian has been dating Australian singer and actress Delta Goodrem. McFadden and Goodrem released a duet, "Almost Here", which reached #3 in the UK charts in February 2005, and also #1 in Australia.

He has also dueted with singer LeAnn Rimes with a song called "Everybody's Someone". The song is expected release in October 2006.
