From the magnetic properties of old neutron stars we propose that an observation of a sufficiently old pulsar limits any ''grand unified theory'' heavy magnetic monopole flux in the pulsar neighborhood to below 5 x 10/sup -24/tau/sub 10/ /sup -2/cm/sup -/ /sup 2/sr/sup -1/sec/sup -1/, where tau/sub 10/ is the age (in 10/sup 10/ yr) of the pulsar's present magnetic field and monopole speeds are approx.10/sup -3/ c. For the millisecond pulsar PSR 1937+214 a major improvement over the Parker limit is obtained, which is also better than various limits from monopole catalysis of baryon decay, provided tau/sub 10/> or approx. =10/sup -1/. The consideration of monopole dynamics inside superconducting neutron-star cores leads to this conclusion.
