EcoCentro Expositor Querétaro, Motorsport racing track in El Marqués, Querétaro, Mexico.

EcoCentro Expositor Querétaro is an exposition center in El Marqués whose racing circuit has two layouts: a 2.314 km road course and a 1.283 km paper-clip oval. The two share Turns 1–2, flat on the oval, before the road course splits into a double hairpin and esses and rejoins on the main straight, also used as a 0.700 km dragstrip.

The EcoCentro Expositor opened in 2001 under President Vicente Fox. Its racing track was inaugurated on 30 March 2008, replacing an earlier Querétaro circuit that had held NASCAR Mexico Series races from 2004 to 2007. The paper-clip oval was added in October 2009.

The venue hosts the annual Querétaro fair in November and December and the El Marqués fair, alongside race weekends. Waldemar Coronas of Argentina was the first foreign driver to win here in the NASCAR Mexico Series, and as of 2025 Rafael Martínez holds the most wins at the circuit with six.

The road course and the paperclip-shaped oval share Turns 1-2, where the oval is flat, while Turns 3-4 are slightly banked; the main straight doubles as a 0.700 km dragstrip for 1/8-mile events.
