José Tomás Ovalle y Bezanilla (Latin American Spanish: [xoˈse toˈmas oˈβaʝe]; December 21, 1787 – March 21, 1831) was a Chilean political figure.

On December 7, 1829, the conservative troops under General José Joaquín Prieto Vial, commander of the southern army, approached Santiago from the South.

On December 14, 1829, General Prieto and his troops met the liberal army under Francisco de la Lastra and defeated them at the Battle of Ochagavía.

Chile was without a leader for a few weeks (from December 7 to 24, 1829) until a Government Junta was organized and took control, in order to avoid the continuance of hostilities, under a neutral José Tomás Ovalle who was acceptable to both sides.

He died a few days later, on March 21, 1831, at 9 AM, and his remains were interred under the altar of the Santiago Cathedral, where they were lost during the renovations of the 19th century and found again in 2004.
