II Zwicky 73 (also known as Zw II 73) is a lenticular and polar-ring galaxy in the constellation Boötes, and about 250 million light years distant from Earth. It is an object of great scientific interest as there have been very few polar ring galaxies discovered. II Zw 73 is a very gas-rich environment. DSS and SDSS images show that it is very similar to polar ring galaxy NGC 660, the best-known of all the polar ring galaxies.

This object is also known as PGC 54461, UGC 9796, MCG+07-31-48, and PRC A-06
