Letitia Alice Walkington (c. 1857 – 28 May 1918) was a pioneering Irish lawyer and a fervent advocate for women's rights, particularly in the realms of education and suffrage. Born in Belfast, Ireland, she was the daughter of Letitia (née Von Heyn) and Thomas R. Walkington. Her father descended from Anglican Bishop Edward Walkington, and her maternal grandfather, Gustav von Heyn, was a Prussian consul and Belfast shipowner. Letitia had at least one sister, Edith, and the family resided on Belmont Road in Strandtown, Belfast.

Initially educated at home by governesses, Letitia began formal schooling at 16, attending boarding schools in England and Paris. In October 1882, she passed the matriculation exam for the Royal University of Ireland. This achievement allowed her to attend classes at Queen's College, Belfast, as women who passed the matriculation exam for the Royal University were permitted to do so. Under the mentorship of barrister Thomas Harrison, she earned a Bachelor of Arts (B.A.) in 1885 and a Master of Arts (M.A.) in 1886, both in Logic, Metaphysics, and Political Economy. She further distinguished herself by obtaining a Bachelor of Laws (LL.B.) in 1888 and a Doctor of Laws (LL.D.) in 1889, becoming the first woman to achieve these degrees in Great Britain or Ireland.

Despite offers from solicitors' offices, Walkington chose to focus on coaching other young women for examinations, given the limited educational opportunities available to them. She collaborated with Frances Helena Gray, another female law graduate, and Miss Hamilton in this endeavor. Additionally, she worked on developing a device for embossing Braille, demonstrating her commitment to accessibility and education.

Walkington was deeply involved in the women's suffrage and temperance movements. In 1889, she participated in the "Congrès International des Œuvres et Institutions Féminines" in Paris as part of the Dublin Women's Suffrage Committee. She co-founded the Belfast Women's Suffrage Society in 1912 with Miss Montgomery, which later became the Women's Political League in 1918, and played a role in establishing the Irish Women's Suffrage Federation. She also served as secretary for the Belfast chapter of the Church League for Women's Suffrage and collaborated with the Irish Women's Temperance Union. Shortly before her death, she was working to form a women's voters union, underscoring her lifelong dedication to women's rights.

Letitia Alice Walkington passed away on 28 May 1918 in Belfast and was laid to rest at Knockbreda Cemetery in County Down. Her trailblazing achievements in law and her unwavering commitment to women's suffrage and education continue to inspire and resonate in the ongoing pursuit of gender equality.
