Ouseburn Farm says is needs to attract 'external finding' if it is to survive.
It's after the Board of Tyne Housing Association - who helped fund the farm - annouced they will no longer be able to do so after 2017.
Tyne Housing has contributed over £100,000 of the farms annual running costs for the last eight years.
The farm is in the Lower Ouseburn Valley in Byker and was set up in 1973.
It's a registered charity and looks after cows, pigs, sheep, goats, ducks and other livestock.
There are classrooms on site that allow school children to visit, as well as vulnerable and disadvantaged people - allowing them often to experience 'farm life' for the first time.
Newcastle City Council says it will do all it can to help find alternative funding.
In the meantime the farm is open as usual.
