This is a list of the British Academy Television Awards for Best Actress. The British Academy Television Awards began in 1955. The Best Actress award was initially given as an "individual honour", without credit to a particular performance, until 1969, when Wendy Craig won for her performance in Not in Front of the Children. Since 1970, nominees have been announced in addition to the winner, and are listed, with the winner highlighted in blue. The Actress category was split into Leading Actress and Supporting Actress, starting in 2010.

The BAFTA TV Awards, or British Academy Television Awards, are presented in an annual award show hosted by the BAFTA. They have been awarded annually since 1955.
