Despite the row in the wake of Griffin's appearance on Question Time last year, he will appear again at the height of the general election campaign in the spring.
The BBC said "alongside" the TV debate between leaders Gordon Brown, David Cameron and Nick Clegg, they are to hold a "minor parties debate".
The corporation's website said: "There will be arrangements in the programming around the BBC debate, a week before polling day, to ensure other parties which have demonstrated they have some electoral support - UKIP, the Green Party and the BNP - will have their say."
Bnp activists hailed it as a victory for the far-right group. Deputy leader Simon Darby said it was a "good idea to go head to head with the Greens and UKIP".
After the Question Time bust-up, Darby also claimed the BBC are taking a softer line with the BNP in programmes.
He said an edition of Panorama will feature the far right in the next few months and added: "Unlike some of the previous encounters between the two bodies I think this will be relatively straightforward. But with these guys you never really know."
Anti-fascist group Searchlight called the plan an outrage. A spokesman said: "Executives at the BBC have become obsessed with giving the BNP national publicity at the licence fee payer's expense.
"These are supposed to be serious debates allowing people to make an informed choice. Nick Griffin has no place there." Griffin's BBC Question Time spot turned into a disaster for the Beeb and the BNP.
Riots broke out in front of the corporation's HQ after Griffin boasted it would "propel the BNP into the big time".
But once the cameras began rolling nervous Griffin, 50, squirmed and bizarrely claimed EU laws meant he "could not explain" why he once denied the Holocaust. Justice Minister Jack Straw said: "We've seen that the moment anyone puts an uncomfortable quote to him he wriggles. He wants to wriggle out of it."
Cambridge-educated Griffin was elected as a Euro MP last July.
