Occurs on relatively fertile plains in low rainfall areas, from the Wimmera east to south of Benalla and north into New South Wales, with scattered southern outliers near Bacchus Marsh, Melton, and Woodlands Historic Park at Greenvale.

Eucalyptus microcarpa is highly variable in shape and size of juvenile leaves, age at which coppice leaves turn from dull blue-green to glossy green, length of pedicels and length and shape of capsule. It intergrades with E. albens in the eastern and central parts of its Victorian distribution and populations with some attributes of both species occur, e.g. at Maryborough, Greytown State Forest, Benalla.
