'''NGC 4911''' ist eine [[Balken-Spiralgalaxie]] vom [[Hubble-Sequenz|Hubble-Typ]] SBbc mit [[Aktiver Galaxienkern|aktivem Galaxienkern]] im Sternbild Haar der Berenike am Nordsternhimmel. Sie ist schätzungsweise 357 Millionen [[Lichtjahr]]e von der [[Milchstraße]] entfernt und hat einen Durchmesser von etwa 140.000 Lichtjahren. Vom [[Sonnensystem]] aus entfernt sich die Galaxie mit einer errechneten [[Radialgeschwindigkeit]] von näherungsweise 5.000 Kilometern pro Sekunde.

Gemeinsam mit [[PGC 83751]] bildet sie das ''Galaxienpaar Holm 499''.

Das [[Astronomisches Objekt|Objekt]] wurde am 11. April 1785 von dem deutsch-britischen [[Astronom]]en [[Wilhelm Herschel|Friedrich Wilhelm Herschel]] entdeckt.<ref>[http://cseligman.com/text/atlas/ngc49.htm#4911 Seligman]</ref>
