Trans-Mexican Volcanic Belt (TMVB) is one of the largest continental volcanic arcs of the North American plate spanning about 1000 km from the Pacific to the Gulf of Mexico. I report here a detailed paleomagnetic study of more than 400 oriented samples coming from 68 independent cooling. All these sites were recently dated by means 40Ar-39Ar systematics and span from 5 Ma to present. Most samples belong to the Western part of TMVB while 18 sites were collected at the Golf of Mexico. Rock-magnetic experiments which included continuous susceptibility and hysteresis measurements point to simple magnetic mineralogy. In most of cases, the remanence is carried by Ti-poor titanomagnetite of pseudo-single-domain magnetic structure. The characteristic paleodirections are successfully isolated for 62 units.
