We have determined the Lamb shift of the He 2{sup 1}S{sub 0}, 3{sup 1}P{sub 1} states by unambiguously establishing the 2{sup 1}S{sub 0} absolute level position, by Doppler-free, two-photon transitions from 2{sup 1}S{sub 0} to n{sup 1}D{sub 2} (7{le}n{le}20). The Lamb shift of 0.093 761(5) cm{sup {minus}1} (2810.88(15) MHz) agrees with less precise experiments, but differs from theory by 98.36(15) MHz.
