We report high angular resolution, multiepoch radio observations of the young pulsar PSR B1800-21. Using two pairs of data sets, each pair spanning approximately a 10 year period, we calculate the proper motion of the pulsar. We obtain a proper motion of μα=11.6+/-1.8 mas yr-1, μδ=14.8+/-2.3 mas yr-1, which clearly indicates a birth position at the extreme edge of the W30 supernova remnant. Although this does not definitively rule out an association of W30 and PSR B1800-21, it does not support an association.
