Luis Antonio Folgueras y Sión (13 December 1769 in Villavaler, León – 1850 in Granada) was a Spanish ecclesiastic, first Bishop of the Roman Catholic Diocese of San Cristóbal de La Laguna and archbishop of Granada.

He was selected as the first bishop of the newly created diocese of San Cristóbal de La Laguna on June 24, 1824, and was confirmed the following September 27.

He founded the Diocesan Seminary of La Laguna in 1832, closing for economic problems in 1834.

After its transfer to Granada, the seat of Tenerife remained vacant, happening to the administrative tutelage of the Roman Catholic Diocese of Canarias until the signature of Concordat of 1851.

[1] To date he has been the longest-serving bishop of San Cristóbal de la Laguna, with 24 years of pastoral service.
