The Monte Carlo technique is used to calculate the order parameter, Phi , of the four-dimensional spin-<sup>1</sup>/<sub>2</sub> Ising ferromagnet in a simple hypercubic lattice. The order-parameter data are described by Phi (t)=B(-t)<sup>1/2</sup> mod ln(-t) mod <sup>1/3</sup>(1+Q ln mod ln(-t) mod / mod ln(-t) mod ) in the range 0.01<or approximately=-t identical to (T<sub>c</sub>-T)/T<sub>c</sub><0.56 with parameters B=1.543+or-0.002 and Q=-0.030+or-0.02. The form of Phi (t) agrees with that predicted by renormalisation group theory.
