Eucalyptus litorea is a mallee that grows to a height of and forms a
lignotuber. It has rough, hard, fissured bark on most or all of the trunk, smooth grey bark above. Young plants and
coppice regrowth have greyish-green, egg-shaped leaves that are long and wide. Adult leaves are arranged alternately, the same glossy green on both sides, lance-shaped, long and wide on a
petiole long. The flower buds are arranged in leaf axils in groups of seven on an unbranched
peduncle, the individual buds
sessile or on
pedicels up to long. Mature buds are oval to spindle-shaped, about long and wide with a conical to beaked
operculum long. The flowers are white and the fruit is a woody, cylindrical or barrel-shaped
capsule long and wide with the valves enclosed below the rim of the fruit. ==Taxonomy and naming==
