Charmless B decays at CDF

In this paper I review the most recent CDF II results in the field of charmless B decays: the measurement of the relative branching fractions of B0 and decays, the direct CP asymmetry in the B0→K+π− decay, the limits on the branching fractions, the first evidence of decay and the measurement of direct CP asymmetry in the B+→ϕK+ decay.
