The Cryogenic Underground Observatory for Rare Events (CUORE) at Laboratori Nazionali del Gran Sasso of INFN in Italy is an experiment searching for neutrinoless double beta (

0 ν β β

) decay. Its main goal is to investigate this decay in

{}^{130}{Te}

, but its ton-scale mass and low background make CUORE sensitive to other rare processes as well. In this Letter, we present our first results on the search for

0 ν β β

decay of

{}^{128}{Te}

, the Te isotope with the second highest natural isotopic abundance. We find no evidence for this decay, and using a Bayesian analysis we set a lower limit on the

{}^{128}{Te}

0 ν β β

decay half-life of

T_{1 / 2} > 3.6 \times 10^{24} yr

(90% CI). This represents the most stringent limit on the half-life of this isotope, improving by over a factor of 30 the previous direct search results, and exceeding those from geochemical experiments for the first time.
