  We present the results of a search for pulsed TeV emission from the Crab
pulsar using the Whipple Observatory's 10 m gamma-ray telescope. The direction
of the Crab pulsar was observed for a total of 73.4 hours between 1994 November
and 1997 March. During this period the Whipple 10 m telescope was operated at
its lowest energy threshold to date. Spectral analysis techniques were applied
to search for the presence of a gamma-ray signal from the Crab pulsar over the
energy band 250 GeV to 4 TeV. We do not see any evidence of the 33 ms
pulsations present in other energy bands from the Crab pulsar. The 99.9%
confidence level upper limit for pulsed emission above 250 GeV is derived to be
4.8x10^-12 cm^-2 s^-1 or <3% of the steady flux from the Crab Nebula. These
results imply a sharp cut-off of the power-law spectrum seen by the EGRET
instrument on the Compton Gamma-Ray Observatory. If the cut-off is exponential,
it must begin at 60 GeV or lower to accommodate these upper limits.
