Julia Lorraine Hill (known as Julia Butterfly Hill, born February 18, 1974) is an American environmental activist and tax redirection advocate. She lived in a 200-foot (61 m)-tall, approximately 1000-year-old California redwood tree for 738 days between December 10, 1997, and December 18, 1999. Hill lived in the tree, affectionately known as Luna, to prevent Pacific Lumber Company loggers from cutting it down. She ultimately reached an agreement with the lumber company to save the tree.
She is the author of the book The Legacy of Luna and co-author of One Makes the Difference.
