Multistep laser-resonance-ionization spectroscopy of tellurium (Te) has been performed at TRIUMF's off-line laser ion source test stand. Six clean and regular even-parity Rydberg series $5p^3$ ($$^{4}S^0_{3/2}$$) np $$^{3}P_{ 0,1,2}$$, n p $$^{5}P_{1,2}$$, and nf $$^{3}F_{2}$$/$$^{5}P_{1,2}$$ were observed. The ionization potential of Te was extracted from the measured series as 72669.110(44)stat(20)sys cm-1. Excited from two different intermediate levels, seven odd-parity autoionization Rydberg series converging to the $5s^25p^3$ ($$^{2}D^0_{3/2}$$) core state of Te were obtained. Three of them are first time reported in the energy range of 92940 cm-1.
