Agnes Kimball (October 1881 – January 5, 1918) was an American soprano. She was a highly popular recording artist in the United States during the 1910s, and is best remembered for recordings she made during the first half of that decade with the Victor Talking Machine Company, Columbia Records, and Edison Records. A classical vocalist, her repertoire encompassed opera, operetta, musical theatre, art songs, and popular ballads; all genres which were in demand among American consumers during that period in history. Many of these recordings are included in the collection of the Library of Congress, and the Discography of American Historical Recordings has catalogued her work.

In live performance, Kimball spent the majority of her career working as a paid church singer. Born in Indiana, she began her career as a professional church vocalist in the early 1900s at Tabernacle Presbyterian Church in Indianapolis. When her husband took a position with Carnegie Steel she became a paid singer at Third Presbyterian Church in Pittsburgh. By 1910 she had moved to New York City and was working as a singer at Brick Presbyterian Church where she was a highly paid vocalist for several years. While she recorded pieces from operas and musicals, she never appeared in stage productions during her career. However, she did spend two seasons touring with Victor Herbert and his light opera orchestra in concerts in 1911–1912. She also toured and recorded with the Croxton Quartet, and worked as an oratorio singer on the concert stage as a member of the Oratorio Artists Quartet. At the time of her death in 1918 she was a resident singer at St. Mark's Episcopal Church in Toledo, Ohio.
