Viloria knocked Marquez down with a right late in round one and continued to dominate the early rounds, before a flurry from the Mexican in the fifth forced him onto the defensive.
When Viloria put Marquez on the floor for a third time with a left to the head in the 10th, Marquez's corner threw in the towel.
On the undercard, Nicaragua's Roman Gonzalez defended his WBA world light-flyweight title against Mexican Juan Francisco Estrada.
Gonzalez claimed a unanimous decision with the judges scoring it in his favour by margins of 116-112 twice and 118-110.
The 25-year-old is now 34-0 (28KO) as a professional.
