Shipquay Street, in the heart of the walled city, will be transformed into a three-lane slide for two days in September as part of a Cancer Research UK fundraiser.
Environment Minister Mark H Durkan helped launch the charity event on Friday.
"Derry people are always willing to get involved, always willing to make an eejit of themselves all for a good cause," he said, after taking a bucket of water to the face.
"It won't be the first splash I've made but hopefully everyone is happy with this one!"
The fundraiser is taking place from 6 to 7 September and comes after a similar event in Bristol recently drew thousands of spectators - on a street nowhere near as steep as Shipquay Street.
Sharon Arbuckle, Cancer Research, said: "It's one of Europe's steepest streets. When you say to people 'imagine Shipquay Street, imagine a waterslide', people immediately say I want to do that!
"It's a slippery street to slide upon. Taking part in something that's amazing fun for a great cause, at the end of the day there's hardly a family anywhere who hasn't been affected by cancer."
Volunteers are being asked to gather donations to take part. There are also medical guidelines - children under the age of 16 and pregnant women will not be allowed.
Anyone who wants to get involved must register before 26 August, but places are limited.
