The present status of pentaquark spectroscopy in lattice QCD is reviewed. The current lattice simulations seem to give no indication of a pentaquark in the positive parity channel to be identified with the Θ+ (1540). However, the negative parity channel can easily accommodate a pentaquark with a mass close to the experimental value. Remark that all present results should be regarded as exploratory.
