The strange contribution to the electric and magnetic form factors of the nucleon is determined at a range of discrete values of Q² up to 1.4 GeV². This is done by combining a recent analysis of lattice QCD results for the electromagnetic form factors of the octet baryons with experimental determinations of those quantities. The most precise result is a small negative value for the strange magnetic moment: GMˢ(Q²=0)=-0.07±0.03μN. At larger values of Q² both the electric and magnetic form factors are consistent with zero to within 2 standard deviations.
