Amelia Lyn "Amy" Acuff (born July 14, 1975) is a track and field athlete from the United States.

Born in Port Arthur, Texas, she established herself domestically with wins at the USA Outdoor Track and Field Championships in 1995 and 1997.

Her personal best is 2.01 m, which she achieved at the Weltklasse Golden League international track and field meet in Zürich, Switzerland, on August 15, 2003.

She was the subject of modeling projects, media stories, and photography relating to her sports career as a track and field athlete.

A new challenge was taken in 1999 as she successfully organized the making of the 2000 Omnilite Millennium Calendar of Champions, which featured nude/semi-nude photographs of Acuff and 11 other U.S. female track and field stars, with half the proceeds going to the Florence Griffith-Joyner Youth Foundation.
