3C 191 is a quasar located in the constellation Cancer. It is located at redshift z = 1.95 and is hosted by an elliptical galaxy. The quasar contains a radio jet known to contain a high rotation measure with a thin shell configuration created in a form of wind inside the central regions.

According to studies, the quasar is producing energy outflow winds with a rate of 1.9 x 10 ergs s. The elliptical host of 3C 191, is said to have a gas density of ~ 0.17 cm with a magnetic field measuring ~ 2.5 x 10 μG. In additional, 3C 191 contains a number of absorption lines.
