Bartosz Białkowski is a Polish football goalkeeper, currently with Championship club Southampton.

On 28 September 2009 he joined Championship strugglers Barnsley on a week-long emergency loan. He played in two Championship matches, then returned to Southampton in League One. On 24 November he made his first league appearance for Southampton in over two years, replacing the injured Kelvin Davis in the 61st minute of the match against Hartlepool. He started the following six matches until Davis recovered from his injury. With Bialkowski's contract set to expire in June, Southampton offered him an extension in May 2010.

In June 2010, he was reported to have signed for Portuguese side S.C. Braga but on 25 June he denied this, saying "I will be back at Southampton for the start of the season and I am hoping to stay with them." On 5 August, Bialkowski signed a two year contract extension with Southampton, with the option to extend it another two years.
