Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two. Both faint, elongated, a little brighter in the middle, resolvable." The other object Herschel referred to is NGC 3193.
NGC 3190 is listed as No. 316 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "edge-on spiral shows signs of interaction."

The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads EON,BM,EQDKLN,DSKWPD.
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the NGC 3190 Group is a part of the Leo II Cloud Complex. The five brightest members of the NGC 3190 Group are NGC 3227, NGC 3190, NGC 3162, NGC 3193 & NGC 3226.
One of a cluster of four galaxies in the Sickle of Leo, between Gamma and Zeta Leonis. These galaxies form an attractive sight in the low-power field of a large telescope. NGC 3190 is about 11th magnitude and 4' long, and has a dark band of material cutting across its equatorial plane. The band shows well in a sketch made with a 16" reflector published in the Webb Handbook.
Hartung describes this edgewise spiral as about 2' long and quite narrow, in PA 120 . He contrasts it with NGC 3193, 6' north following. He remarks that 3190 is much brighter towards the centre, and is plainly seen with a 6-inch. Other members of the cluster are NGC 3193, 3185 and 3187.
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 3' x 1' extent; fairly bright and large; nearly edge-on; axis oriented NW-SE; equatorial dust lane; N3193 (12M; 2' diameter) 10' NE with 8.5M star 80" to N; N3187 (13M; 3' x 1' extent) 10' to NW; SP GAL N3185 (13M; 2' x 1' extent) 20' SW (see photo @ HAG-43); great group!."

[10h 18m 6s, 21° 50m 0s] Just 10' west of NGC 3193. Part of a cluster of galaxies, but the skies were hazing up and it was difficult to see more members. Need to revisit this one.
