Eight episodes will be filmed in the famous party-spot and the cast - Jay Gardner, Gaz Beadle, James Tindale, Vicky Pattison, Holly Hagan, Sophie Kasaei, Charlotte-Letitia Crosby, Ricci Guarnaccio, Rebecca Walker - will be "living it up Geordie-style" in their own luxury villa.
Beach contests, pool parties and super nightclubs will fill up the reality TV stars' time, but they must also pay their way with part-time work during the trip.
The Cancun Spring Break third series will air in the summer.
Last summer, the cast visited Magaluf for a double episode special.
Series two of Geordie Shore is currently airing on Tuesday nights at 10pm on MTV.
