Her body was found yesterday in a tent near Gilabbey Park in the south-west of the city.
Gardaí at the Bridewell Station said the death was sudden but was not being treated suspiciously.
The death was confirmed as it was revealed the Government is preparing to convene an emergency housing summit next week in the wake of two others deaths of homeless people, in Dublin and Kildare, earlier this week.
Meanwhile, new figures have revealed that 165 children are homeless in the Cork region.
Paul Sheehan, spokesman for Cork Simon, said the crisis continues to worsen. When the government officially started recording figures in January 2015, there were 13 families, including 26 children without homes.
He said: “It does have a long-lasting impact on children. We see a lot of people in our emergency shelters who have had very traumatic childhoods and that would be one of the overriding causes for their homelessness, so you can only guess what the future holds for children who are now stuck in this type of emergency accommodation and stuck there for far too long,” he said.
In January 2016, 34 families were homeless — 40 of those adults and 77 of them children.
The latest department data shows 61 families were living in emergency accommodation — 79 adults and 165 children. “These are the figures published by the Department of Housing and they reflect what’s happening nationally. They also mirror the number of adults that are in emergency accommodation. That is continuing to rise,”
Mr Sheehan said. There are two types of emergency accommodation — shelters, which are full every night and sometimes overflowing — and private accommodation, which consists of rooms in hotels and B&Bs.
