A novel maize variety designated X80H134 and seed, plants and plant parts thereof are produced by crossing inbred maize varieties. Methods for producing a maize plant by crossing hybrid maize variety X80H134 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X80H134 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the maize variety X80H134, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X80H134. This invention further relates to methods for producing maize varieties derived from maize variety X80H134.
