El Toro, a Spanish term meaning The Bull, is a wooden roller coaster at Six Flags Great Adventure in Jackson, New Jersey. Designed by Intamin of Switzerland, it opened to the public on June 11, 2006. Intamin also worked with members of Rocky Mountain Construction to build the ride. When it opened, it had the steepest drop of any wooden roller coaster in the world at 76 degrees, until the record was broken by T Express in 2008 by one degree. Overall, its structure height of 181 ft is ranked third, its drop height of 176 ft is ranked first, and its top speed of 70 mph is ranked first among all wooden roller coasters in the world. It is also the first wooden roller coaster to use a cable lift as opposed to the traditional chain lift.

El Toro is the main attraction of the Mexican-themed section, Plaza Del Carnaval. Some of the ride's track is located in Rolling Thunder's infield. It replaced the Viper roller coaster that closed in 2004.
