The 2006 ATS Formel 3 Cup season was a multi-event motor racing championship for single-seat open wheel formula racing cars that held across Europe. The championship featured drivers competing in two-litre Formula Three racing cars built by Dallara, Ligier, Lola and SLC which conform to the technical regulations, or formula, for the championship. It was the fourth edition of the ATS F3 Cup. It commenced on 22 April at Oschersleben and ended on 1 October at the same place after ten double-header rounds.
