NGC 6729 (also known as Caldwell 68) is a reflection/emission nebula of the Corona Australis Molecular Cloud in the constellation Corona Australis. It was discovered by Johann Friedrich Julius Schmidt in 1861.

This fan-shaped nebula opens from the star R Coronae Australis toward the star T CrA to the south-east. R CrA is a pre-main-sequence star in the Corona Australis molecular complex, one of the closer star-forming regions of the galaxy at a distance of 130 pc. NGC 6729 is a variable nebula which shows irregular variations in brightness and in shape.
