By using high-magnetic fields (up to 60 tesla), we observe compelling evidences of Integer Quantum Hall Effect in trilayer graphene. The magnetotransport fingerprints are similar to that of the graphene monolayer, except the absence of a plateau at filling factor ν = 2. At very low filling factor, the Hall resistance vanishes due to the presence of mixed electron and hole carriers induced by disorder. The measured Hall resistivity plateaus are well reproduced theoretically, using a selfconsistent Hartree calculations of the Landau levels and assuming and ABC stacking order of the three layers.
