'''NGC 6355''' is a [[globular cluster]] located in the constellation [[Ophiuchus]].<ref name=In-the-sky>{{cite web|title=The globular cluster NGC 6355|url=https://in-the-sky.org/data/object.php?id=NGC6355|website=In-the-sky|access-date=31 October 2016}}</ref> It is at a distance of 28,000 light years away from Earth, and is currently part of the [[Galactic bulge]].<ref name=Souza/>

NGC was discovered by the German-born British astronomer [[William Herschel]] on 24 May 1784.<ref name=cseligman>{{cite web|title=NGC 6355 (= GCL 63)|url=http://cseligman.com/text/atlas/ngc63a.htm#6355|website=cseligman|access-date=14 October 2015}}</ref> It was initially thought to be an [[open cluster]], but its true nature as a globular cluster was later confirmed. It is a [[core collapse (cluster)|core-collapse]] cluster.<ref name=Souza/>
