Fighting Network Rings, trademarked as RINGS, is a Japanese combat sport promotion that has lived three distinct periods: puroresu promotion from its inauguration to 1995, mixed martial arts promotion from 1995 to its 2002 disestablishment, and the revived mixed martial arts promotion from 2008 onward.

In molecular biology, a RING (Really Interesting New Gene) finger domain is a protein structural domain of zinc finger type which contains a Cys₃HisCys₄ amino acid motif which binds two zinc cations. This protein domain contains from 40 to 60 amino acids. Many proteins containing a RING finger play a key role in the ubiquitination pathway.
