The extra cash follows a combination of a rise in lottery ticket sales and revised financial forecasts from the Big Lottery Fund.
Speaking at the Big Meet, the Big Lottery Fund's first national grantholder conference at Hampden Stadium in Glasgow, Finance Secretary John Swinney said:
"This significant investment can serve as a magnet for transformational change in Scotland if effectively targeted towards those most in need. We will continue to make the case for the £150 million in lottery monies, diverted to help fund the London Olympics, to be returned to Scotland.
"The return of this money, combined with the welcome additional investment announced today, would give a real boost to Scotland's communities. The Scottish Government looks forward to working with the BIG Lottery on ensuring this resource makes a real difference to Scotland."
Big Lottery Fund Scotland Director Dharmendra Kanani said: "We have a powerful community attending our conference today, each of whom makes a positive difference to people's lives every day all across Scotland. Our Investing in Communities portfolio has supported this inspirational group in creating their legacy.
"£400 million over five years is a formidable sum, but poverty and disadvantage can prove immune to cash alone. We will invest in people and their communities to tackle die-hard need and use the opportunity we now have to shift the balance of power back into communities themselves."
The Big Lottery Fund is the largest distributor of National Lottery good cause funding. Through its Investing in Communities portfolio BIG in Scotland has made 393 awards totalling more then £134 million over the last three years.
