The study of (multi)strange hadrons and resonance production allows in heavyion collisions to gather information on the early partonic phase of the fireball and its evolution. The ALICE collaboration has measured the production of K*(892)0, φ(1020) resonances and KS0, Λ, Ξ−, Ω− hadrons and their anti-particles at mid-rapidity in Pb–Pb collisions at √sNN = 2.76 TeV. This contribution presents results on strangeness enhancement, baryon to meson ratios (Λ/KS0 and Ω−/φ) and on resonance to stable particle ratio (φ/K and K*/K). The nuclear modification factor RAA of the φ(1020) will be also discussed.
