The electron affinity of tellurium has been determined to 1.970 876(7) eV. The threshold for photodetachment of Te^-(^{2} P_{3/2}) forming neutral Te in the ground state was investigated by measuring the total photodetachment cross section using a collinear laser-ion beam geometry. The electron affinity was obtained from a fit to the Wigner law in the threshold region.
