Ivy Williams (7 September 1877 – 18 February 1966) was the first woman to be called to the English bar, in May 1922.

After the Sex Disqualification (Removal) Act 1919 came into force in December 1919, which abolished the prohibition on women becoming barristers, she joined the Inner Temple as a student on 26 January 1920 after Theodora Llewelyn Davies.

Her call to the bar was described by the Law Journal as "one of the most memorable days in the long annals of the legal profession".

[7] In 2020, barrister Karlia Lykourgou set up the first outfitter dedicated to offering courtwear for women.

[8] A blue plaque to her memory was installed on her home at 12 King Edward Street, Oxford on 21 September 2020.
