NGC 3195 is a planetary nebulae located in the constellation Chamaeleon. It is the most southern of all the bright planetary nebula in the sky, and remains completely invisible to all northern observers. First discovered by Sir John Herschel in 1835, this sizable and slightly oval 40×35 arcsec planetary nebula 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.
