The former Labour member will participate as a candidate in Tuesday’s hustings starting from 6:30pm. The livecast will focus on candidates from the South of Scotland list region.
The SNP’s Paul McLennan, Craig Hoy from the Scottish Conservatives, and Scottish Greens’ candidate Laura Moodie are among the confirmed guests.
The other confirmed candidates are Labour’s Carol Mochan and Catriona Bhatia from the Scottish Liberal Democrats.
Mr Galloway, who is standing as part of the All for Unity party in May’s elections, is hoping to win a seat in the South of Scotland region and has voiced his opposition to independence.
He suspended his election campaign on Friday as police investigate alleged death threats against him, but has pledged to still take part in The Scotsman’s online election hustings “from a remote location”.
Mr Galloway was last week been at the centre of a social media row, having drawn criticism after posting a message on Twitter that appeared to be directed at justice secretary Humza Yousaf.
The All for Unity party was launched in February last year by Mr Galloway, who issued a "Save Our Scotland" plea as he urged people to back his new movement.
The eight-part hustings series led by host Gina Davidson is running in the countdown to the Scottish elections on May 6.
The Scotsman is taking viewers from their own homes, living rooms and offices, across the length and breadth of the country as we visit all eight parliamentary regions.
They can also submit questions for the candidates by emailing them to [email protected] and including their full name, age, location and occupation.
Questions can also be asked live during the hustings on The Scotsman’s Facebook page.
