Natasha Maria Hamilton (born July 17, 1982, Liverpool, United Kingdom) is a British singer and former member of Atomic Kitten.

Natasha started singing and performing from an early age and was inspired by Barry White. After Heidi Range left the early band Natasha was offered the opportunity to replace her. Natasha dated Fran Cosgrave, a club owner and former bodyguard of Westlife, and they had baby Joshua Hamilton-Cosgrave in August 24, 2002. The pair split shortly after. On January 23, 2004 Natasha left the band because combining the band with her personal life became too much for her and she wanted to spend more time with her son. On December 31, 2004, Natasha gave birth to her second son, Harry Hatcher-Hamilton whose father is Gavin Hatcher. In July 2005, Natasha and Gavin split and she was recently reunited with Cosgrave. The pair are now engaged.
