'''NGC 6723'''是在[[人馬座]]的一個[[球狀星團]]<ref name="simbad" />，位置在靠近[[南冕座]]的交界處。它的視星等在6至6.8等，直徑在7和11弧分，在[[夏普力-索耶集中度分類法]]的類型為VII，星團中的恆星星等為14等。

與常見的球狀星團不同，NGC 6723具有較高的[[金屬量]]和大量年輕恒星，原始恒星僅占總數的0.363{{±|0.017}}%<ref>{{citation|arxiv=1908.06670|year=2019|title=Multiple Stellar Populations of Globular Clusters from Homogeneous Ca–CN–CH Photometry.
