Judith Alison Hill (born 30 October 1959) is an Irish architectural historian, built heritage consultant and author, best known for her biography of Anglo-Irish dramatist and folklorist Lady Gregory.

Hill has published widely on art and architectural history, and appeared on Irish TV and radio, most recently in the two-part RTÉ documentary on Lady Gregory starring Miriam Margolyes and Lynn Ruane.

[4] In The Times Literary Supplement, Declan Kiberd wrote: "Judith Hill, a noted architectural historian with a deep feeling for the houses in which this story is enacted, does very well in raising Gregory's profile as a cultural revivalist, but she also makes a spirited case for her as a folk artist.

"[5] In Books Ireland, Robert Greacen wrote: "Judith Hill, in this well-researched and lucidly written biography ... reveals the passionate woman behind the cold, sombre mask.

In short it brings to vivid life the story of a remarkable Irishwoman who, in a farewell note to Yeats, could truly say, “I have had a full life.”[6] Books: Local Government, Dublin, 2008).
