The party will run candidates in every seat on a campaign for stronger climate action, affordable housing and integrity in politics.
It says it hopes not only to increase its representation but hold the balance of power in the Legislative Council.
Party leader Samantha Ratnam heads the five-woman, three-man ticket and will re-contest Northern Metropolitan Region.
Port Phillip councillor and former environmental lawyer Katherine Copsey will challenge for Southern Metropolitan, Geelong councillor Sarah Mansfield for Western Victoria and Maribyrnong councillor Bernadette Thomas in Western Metropolitan.
Cate Sinclair will run in Northern Victoria and former federal candidate Mat Morgan for Eastern Victoria.
The Greens received more than 10 per cent of the primary vote in the upper house in Victoria's last elections, but preferences saw only one MP elected.
"If the will of voters had been reflected in 2018, the Greens would have at least four upper house MPs right now," Ms Ratnam said in a statement on Saturday.
"Yet sadly our broken voting system sees the will of voters distorted through dodgy preference whispering.
"This year we're hoping to build on the momentum of the federal election, where Victorians voted for the Greens in record numbers, and increase our representation in the upper house so we can hold the balance of power."
