Heynckes was speaking ahead of Saturday's home match against Bavarian neighbours Augsburg, at the end of which the champions will receive the Bundesliga trophy.
"It looks like goodbye," said Heynckes, who celebrated his 68th birthday on Thursday and appeared to open the door to retiring from football management altogether.
"Once you have coached a club like Bayern Munich, who break all records, there is not much interest in coaching another team in the Bundesliga," added Heynckes, whose side have lost just one league game all season and have already set a new record for most points in one campaign in Germany's top flight.
Bayern will celebrate winning their 22nd Bundesliga title, and 23rd national championship overall, on Saturday before turning their attentions to the Champions League final against Borussia Dortmund at Wembley on May 25.
They will then have a German Cup final against Stuttgart to prepare for on June 1 as the Bavarians aim to win an unprecedented treble.
Heynckes has already dismissed suggestions that he might return to former club Schalke, where he previously coached in 2003-04, and Real Madrid, whom he
led to Champions League glory in 1998. Madrid are expected to be on the lookout for a successor to Jose Mourinho this summer.
Heynckes' final league game at the helm will be away to Borussia Mönchengladbach, where he enjoyed a glittering career as a player and later began his coaching career
