'''NGC 3619'''（'''UGC 6330'''，'''PGC 34641'''）是[[大熊座]]的[[透鏡狀星系]]<ref name=Silchenko/>。1790年3月18日，[[威廉·赫歇爾]]发现该星系<ref name=cseligman>{{cite web|url=http://cseligman.com/text/atlas/ngc36.htm#3619|title=New General Catalogue objects: NGC 3600 - 3649|author=Seligman, Courtney|website=cseligman.com|accessdate=2021-06-01|archive-date=2019-02-18|archive-url=https://web.archive.org/web/20190218050007/http://cseligman.com/text/atlas/ngc36.htm#3619|dead-url=no}}</ref>。

NGC 3619属于NGC 3642星系群（LGG 234），该星系群共有5个星系<ref>{{cite journal |author1=A.M.Gracias |title=General study of group membership. II.

==特征==
===距离===
根据3个不依赖红移的距离测量，NGC 3619的距离约为{{cvt|31.967 ± 6.504|Mpc|Mly|lk=on|}}。根据不依赖红移的距离（[[NASA/IPAC外银河系数据库|NED]]数据库用哈勃距离测定尺寸），该星系直径约为29.2kpc<ref name=ned/>。
===内部气体===
NGC 3619是个比较特殊的透镜星系。该气体含量较大，中性氢区域比寻常透镜星系密致很多。该星系[[H-α]]谱线分布非常不对称，且分布区域非常大。并且，气体绕星系核的绕转速度于恒星的绕转速度大不相同。因此，可以推断NGC 3619气体盘和恒星盘并不共面。<ref name=Silchenko>{{cite journal|doi=10.3847/1538-4365/ab3415|title=The Gas Kinematics, Excitation, and Chemistry, in Connection with Star Formation, in Lenticular Galaxies|year=2019|last1=Sil'chenko|first1=Olga K.|last2=Moiseev|first2=Alexei V.|last3=Egorov|first3=Oleg V.|journal=The Astrophysical Journal Supplement Series|volume=244|issue=1|page=13|arxiv=1907.07261|bibcode=2019ApJS..244....6S|s2cid=197431133}}</ref>
