The condensate fraction n 0 in superfluid 4 He is determined at seven temperatures in the range 1.00 ≤ T ≤ 2.15 K by analyzing new and highly accurate pair‐correlation functions in terms of the model of Hyland, Rowlands, and Cummings. The results are in good agreement with values of n 0 obtained from a very recent neutron inelastic scattering study and with the best theoretical estimates of n 0 at T = 0
