Agnes Giebel (born August 10, 1921) is a German soprano. She was born in Heerlen, in the Netherlands, where she lived the first years of her life. She studied at the Folkwang Hochschule in Essen and made her first public appearance as a singer in 1947. Her career lasted until the 1990s during which she established a wide-ranging discography.

Giebel's repertoire consisted predominantly of sacred works of music such as cantatas, oratorios, passions, and masses and was considered[who?] to be one of the greatest Bach singers of her generation. As an interpreter of lieder she often performed with the pianist Sebastian Peschko. She is also known for her performance in Beethoven's Ninth Symphony under the direction of Otto Klemperer.

Today Agnes Giebel lives in Cologne. Her daughter, Kristina Kanders, and her granddaughter, Julia Giebel, are also musicians. For the Alois Kottmann Award she is member of the jury panel along composer Richard Rudolf Klein, the violinists Alois Kottmann and Boris Kottmann as well as singer Margit Neubauer.
