Socialist MSP Rosie Kane will be camping out in a make-shift street bedroom to raise cash for the homeless.
She has invited people to join her on Saturday in George Square, Glasgow.
Ms Kane is raising money to support Scotland's Homeless World Cup team which will be taking part in the challenge later this month.
There will be 32 teams competing in the tournament in Gothenburg. Ms Kane said the people taking part were the "pride of Scotland".

SCOTLAND’S health minister Malcolm Chisholm last week hinted that he may reject NHS Argyll and Clyde’s health proposals for this area.
Mr Chisholm has been put under enormous pressure to knock back the clinical review after politicians from all parties backed Scottish Socialist Party MSP Frances Curran in her condemnation of the document.

George McNeilage, a friend of the family, also paid tribute to the teenager during the 50-minute service. Mr McNeilage, secretary of North Pollok community council and an activist with the Scottish Socialist party, revealed that he had tried to talk Fusilier Gentle out of enlisting.
He described the young man as an "economic conscript", but said the teenager had been determined to carve out a career in the forces.
Mr McNeilage recalled: "He told them he wanted to make something out of his life and not be like other teenagers in the schemes who hang around the street corners with nothing to do."
Mr McNeilage added: "He was an economic conscript. He was literally signed up when he went to sign on the buroo. His words to me were: 'Big man, I am only getting a bit of work here and there. At least I'll get my driving licence, I'll get to see parts of the world I wouldn't get to see, I'll get a permanent wage and I might get a trade out of it.'"
Tommy Sheridan, the SSP MSP, also paid his respects.
Neil Mitchell, 63, from Pollok, was one of hundreds of people who listened to the service, relayed outside through loudspeaker.
With tears in his eyes, he said: "My two sons went into the army because there were no jobs around here. They got out safe. But poor wee Gordon, it's a tragedy. He had his whole life ahead of him. I blame the UK government. He should never have been out there."

GMB Change Labour Funding

LABOUR'S general election campaign suffered a potentially devastating blow last night when one of the country's biggest unions announced it would fund MPs directly, with the money only going to those who supported its aims.
The move involves £750,000 of campaign funds and could hinder the re-election chances of any of the 108 Labour MPs – 13 Scottish – who are supported by the GMB but who fail to sign up to the aims of the UK's fourth largest union.
