NGC 3195 is a planetary nebula located in the constellation Chamaeleon. It is the most southern of all the bright sizeable planetary nebula in the sky, and remains invisible to all northern observers. First discovered by Sir John Herschel in 1835, this 11.6 apparent magnitude planetary nebula is slightly oval 40×35 arcsec, and can be seen visually in telescopic apertures of 10.5 centimetres (4.1 in) at low magnifications.

Spectroscopy reveals that NGC 3195 is approaching Earth at 17 kilometres per second (11 mi/s), while the nebulosity is expanding at around 40 kilometres per second (25 mi/s). The central star is listed as >15.3V or 16.1B magnitude, and remains invisible to visual observers. Distance is presently estimated at about 1.7 kpc.
