El Toro is a wooden roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey. Designed by Werner Stengel and manufactured by Intamin, the ride opened to the public on June 11, 2006. Intamin subcontracted Rocky Mountain Construction to build the ride, and the coaster's track was prefabricated, allowing for quicker installation and lower construction costs. El Toro is the main attraction of the Mexican-themed section of the park, Plaza Del Carnaval. It replaced another roller coaster, Viper, which closed following the 2004 season.

A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.
