Geelong East was an electoral district of the Legislative Assembly[1] in the Australian state of Victoria from 1859 to 1985.

It was located south of the city of Geelong, defined in the Victorian Electoral Act, 1858 as: Commencing at the north-western angle of the town reserve of Geelong; thence by a line south to the River Barwon; thence westward and northwestward by the River Barwon to the western boundary of the reserve at the junction of the Moorabool and Barwon; thence east by the northern boundary of section 25, parish of Barrabool; thence south by the eastern boundaries of sections 25 and 11, and by part of the eastern boundary of section 7, all in the same parish; thence south-easterly by a curved line crossing the Waurn Chain of Ponds to the southern boundary of section 3, parish of Conewarre; thence east by the southern boundaries of sections 3 and 4 in the same parish; thence north-easterly by a curved line crossing the River Barwon to the south-eastern angle of section 11 in the parish of Moolap; thence by the eastern boundary of that section and a line north to the shores of Corio Bay; and thence by the shores of Corio Bay to the north-western angle of the town reserve, the commencing point aforesaid, including the remaining portion of the reserve at Point Henry.

[1] After the Electoral district of Bellarine was abolished in 1976, Geelong East was re-created.

In 1985, population increases caused another redrawing of electoral boundaries; Geelong East was abolished and Bellarine re-created that year.

Graham Ernst, last member for Geelong East, represented Bellarine 1985–1992.
