NGC 6356 is a globular cluster located in the constellation Ophiuchus. It is designated as a II in the Shapley–Sawyer Concentration Class and was discovered by the German-born British astronomer William Herschel on 18 June 1784. The star cluster is more dense and bright towards the middle. NGC 6356 is located 80' north east of the brighter NGC 6333. It is at a distance of 49,600 light years away from Earth.{{cite web|title=Object No. 1 - NGC 6356|url=http://ned.ipac.caltech.edu/cgi-bin/objsearch?objname=NGC+6356&extend=no&hconst=73&omegam=0.27&omegav=0.73&corr_z=1&out_csys=Equatorial&out_equinox=J2000.0&obj_sort=RA+or+Longitude&of=pre_text&zv_breaker=30000.0&list_limit=5&img_stamp=YES|website=NASA/IPAC extragalactic database|publisher=NASA/IPAC|access-date=19 October 2015}}{{cite web|title=Revised NGC Data for NGC 6356|url=http://spider.seds.org/ngc/revngcic.cgi?NGC6356|website=Seds|access-date=19 October 2015}}{{cite web|title=NGC 6356 (= GCL 62)|url=http://cseligman.com/text/atlas/ngc63a.htm#6356|website=cseligman|access-date=19 October 2015}}{{cite web|title=NGC 6356|url=http://spider.seds.org/spider/MWGC/n6356.html|website=Seds|access-date=19 October 2015}}{{cite web|title=The globular cluster NGC 6356|url=https://in-the-sky.org/data/object.php?id=5108|website=In-the-sky|access-date=19 October 2015}}

The cluster is relatively metal-rich and therefore has a large amount of interstellar dust in its core.[http://adsabs.harvard.edu/full/1998MNRAS.301L..30H Dust in the core of the metal-rich globular cluster NGC 6356]
