Alonzo Church (April 9, 1793 – May 18, 1862) was the sixth president of the University of Georgia (UGA).

He initially joined the UGA faculty as a Professor of Mathematics and served in that capacity for ten years before assuming the presidency.

Although Church served longer than any president of the University, there were numerous clashes with student and faculty during his tenure which resulted in declines in enrollment and faculty upheaval.

President Church's great-grandson, Alonzo Church, was a renowned Professor of Mathematics; he taught at both Princeton University (his alma mater) and UCLA.

President Church's daughter, Julia, married George Alexander Croom, owner of Casa de Laga Plantation in Tallahassee, Florida, Father of Alonzo Church Croom, Comptroller of the State of Florida from 1900 until his death on December 7, 1912, and brother of Hardy Bryan Croom, a planter and recognized naturalist, who discovered the rare Torreya tree and established Goodwood Plantation.
