We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million $B\bar{ B}$ pairs collected with the BABAR detector at the PEP-II asymmetric-energy $e^+e^-$ collider. We measure the following charge asymmetries: ${ \cal A}_{ CP} (B^{ \pm}\to\eta^\prime K^{ \pm}) = -0.11\pm 0.11\pm 0.02$, ${ \cal A}_{ CP} (B^{ \pm}\to\omega \pi^{ \pm}) = -0.01^{ +0.29}_{ -0.31}\pm 0.03$, ${ \cal A}_{ CP} (B^{ \pm}\to\phi K^{ \pm}) = -0.05\pm 0.20\pm 0.03$, ${ \cal A}_{ CP} (B^{ \pm}\to\phi K^{ *\pm}) = -0.43^{ +0.36}_{ -0.30}\pm 0.06$, and ${ \cal A}_{ CP} (B^{ 0}\to\phi K^{ *0}) = 0.00\pm 0.27\pm 0.03$.
