Gladys Maud Bustamante, OJ (née Longbridge; 8 March 1912 – 25 July 2009) was a Jamaican workers' and women's rights activist and wife of Sir Alexander Bustamante, Jamaica's first Prime Minister. She was a prominent member of the Jamaican trade union movement, and was affectionately known as "Lady B" by Jamaicans. She has been called the "Mother of the Nation" due to her relationship with many of Jamaica's founders. Jamaican Prime Minister Bruce Golding has called Bustamante "an icon of political struggles" in Jamaica's march towards independence.
