Northern Ireland are going to their first major tournament in 30 years after an historic 3-1 victory over Greece.
Michael O'Neill's men finished the job in front of 11,700 frenzied fans at Windsor Park despite being without four key players.
They will now feature at their first ever European Championships in France next year.
Skipper Steven Davis scored two of the history-making goals, with stand-in striker Josh Magennis grabbing the other.
"An unbelievable night," said Davis. "We showed what we were all about, we couldn't ask for it to go any better."
The result, secured in front of local hero Rory McIlroy and boxing champion Carl Frampton, ends a run of 14 unsuccessful qualifying campaigns since Northern Ireland made it to the 1986 World Cup.
The celebrations were jubilant at the final whistle, with O'Neill launched into the air and given the bumps by his players.
But there was agony for Scotland, whose chances of qualification were ended by an injury-time equaliser from Poland.
That result means Republic of Ireland, who beat Germany 1-0, could qualify if they defeat Poland on Sunday.
