Stuart Anderson will take on challenge later this month in aid of the Wolverhampton Wanderers' Foundation and the Good Shepherd Ministry.
Both charities have teamed up to launch the virtual fundraiser to help those most in need – with the original sleepout idea cancelled due to Covid-19.
It comes after more than 100 people spent a night in the Stan Cullis stand at Molineux to raise £50,000 to help rough sleepers and homeless people.
The Wolverhampton South West MP, who took part in last year's event, said: "Reducing food poverty is a key priority, and I welcome the unprecedented level of support that the Government has made available to families in light of the situation regarding coronavirus.
"Our work is not done until food poverty is eradicated, and that is why I am taking part in the Molineux Sleepout 2020 – to raise the profile of this issue and to raise funds for two fantastic local charities.
"I am very grateful to everyone who has already donated, and I would appreciate all support."
Mr Anderson was motivated to get involved after volunteering at the Good Shepherd ever since he moved to Wolverhampton – with the MP also supporting the charitable work of the Wolves Foundation.
Demi Grundy, communications and fundraising manager for Wolves Foundation, has encouraged people to get involved in the virtual event due to the impact of Covid-19.
She said: "So whether fans fancy sleeping in a tent in their garden, or setting up camp somewhere indoors away from their nice warm beds, it would be great to see as many people as possible coming together to show support."
The MP will take on the challenge with his family on November 27 with others. Anyone who wishes to donate can visit https://www.justgiving.com/fundraising/stuart-anderson-mp
