Hilda Tweedy, née Anderson (1911–2005) was an Irish women's rights activist.
A founding member and leader of the Irish Housewives' Association (IHA), she was active for decades advocating for the rights of women on a diverse number of issues including equal pay, girls' education, recycling, the marriage bar (an Irish law that required a woman employed in the civil service to resign her position when she married), the right of women to serve on juries, and other issues.
From 1929 to 1936 she lived in Egypt, starting a PNEU school in Alexandria, and reading for an external mathematics degree from the University of London.
With the onset of World War II she resolved to tackle the effects of wartime food shortages on children.
The organization fought for accessible nutritious food, public health, social welfare, and education for all.
