Nicolás de Vergara el Mozo (1540 - 11 December 1606) was a Spanish sculptor, architect, blacksmith and glassmaker. He worked in the Toledo Cathedral, where he was master of works, and in other religious and civil buildings. He was the son of the architect and sculptor Nicolás de Vergara el Viejo and Catalina de Colonia, and brother of Juan de Vergara. He was also the nephew of the master glassmakers Arnao de Vergara and Arnao de Flandes and grandson of Arnao of Flanders the Elder.
Still in his father's life, the council of the Toledo Cathedral of Toledo named him his sculptor in the year 1573. Together with his father, he performed the two bronze lecterns of the choir of the Cathedral, and when his father died two years later, he worked with his brother Juan de Vergara, to finish the stained glass windows of the cathedral, works that ended in 1580 .
He was appointed twice as the master of the Cathedral, the second time in 1587, remaining in office until his death. He then began the works of the Chapel of the Tabernacle in Herrerian style and was responsible for the traces of the architectural complex of the Chapel of the Tabernacle, Reliquary, Sacristy and courtyard and house of the treasurer. He also made the window of the rosette of the door of the Lions and on the interior facade of the clock door the medallion of the Virgin of the Annunciation.
On these dates he made with the teachers Juan Bautista Vázquez el Viejo and Juan Correa de Vivar (painting) the main altarpiece for the church of Santa María Magdalena de Mondejar (Guadalajara) designed by Alonso de Covarruvias. This great and great work today does not exist since it was destroyed in the Spanish Civil War, being able to admire in the same location, an exact copy of the pictorial and sculptural set in all its original magnitude and quality.
