Abstract
We review the methodology of searches for planet-mass bodies around ne utron stars observable as radio pulsars and discuss the current status of these searches. PSR B1257+12, a 6.2-millisecond pulsar, remains th e only neutron star accompanied by confirmed planets. It is possible t hat there is a fourth distant planet in the 1257+12 system. The best o f the other candidates for pulsar planets under consideration is a dis tant, possibly Jovian-mass companion to PSR B1620-26, a 11-millisecond pulsar in the globular cluster M4.
