Thomas de Vallgornera (born in Catalonia about 1595; died 15 September 1665) was a Spanish Dominican theologian and ascetical writer.
He was a member of the convent of Barcelona, and for some time, while Catalonia was subject to the French, was its vicar-general, about 1642.
His principal work is a mystical theology first published at Barcelona in 1662 under the title Mystica theologia D. Thomae, utriusque theologiae scolasticae et mysticae principis, etc.
The work having become rare and difficult to obtain, a new edition was brought out by the Dominican Jean Berthier at Turin, 1890.
The doctrine of the book is the doctrine of Thomas Aquinas, of which the author writes in his prologue: Besides his Mystical Theology Vallgornera is the author of a book on the Rosary of the Blessed Virgin, De Rosario B. Marix Virginis, which appeared at Barcelona about 1662.
