  We investigate the thermodynamic properties of the nonlocal tachyon motivated
by their nonlocal structure in string field theory. We use previously developed
perturbative methods for nonlocal fields to calculate the partition function
and the equation of state in the high temperature limit. We find that in these
models the tachyons undergo a second order phase transition. We compare our
results with those of ordinary scalar field theory. We also calculate the one
loop finite temperature effective potential.
