Marius Žaromskis (born July 30, 1980) is a Lithuanian retired professional mixed martial artist who competed in the Lightweight and Welterweight divisions.

A professional competitor for over 24 years, Zaromskis formerly competed for Strikeforce, Cage Rage, Bellator, DREAM, and also fought at Dynamite!!

Žaromskis began martial arts at around the age of 15 or 16 years old with Kyokushin Karate and kickboxing, becoming a National Youth Champion of Lithuania at both styles.

Žaromskis returned after five years in Essex, England, at UKMMAC 13 against Jack Mason and won by technical knockout.

After that loss, Žaromskis returned against Dariusz Świerkosz at Cage Rage: Contenders 3 and won by submission in the first round.

Zaromskis fought for the company a total of seven times until May 2008 when it was bought by EliteXC who soon fell into bankruptcy, meaning Cage Rage ceased operations.

In the semifinals Žaromskis faced Hayato "Mach" Sakurai, who had just come off a KO victory over WAMMA Lightweight Champion Shinya Aoki in the previous round of the tournament.

Sakurai landed one takedown and assumed the half guard position in the middle of the ring, but Žaromskis was swiftly able to rise to his feet.

When the bout resumed Žaromskis came out with a renewed intensity and after a brief exchange he landed a left high kick that dropped his opponent.

Now in the final, Žaromskis faced Jason High who had defeated Andre Galvao previously that night in the other semifinal bout.

[3] The fight was stopped early into the first round by doctors when it appears Žaromskis' strikes had partially torn Sakuraba's ear from his head.

Ishikawa was out-struck for almost all three rounds and was almost finished several times, but he was able to survive, eventually losing a unanimous decision.

[5] After rocking Diaz earlier, Žaromskis ran into a straight right hand and lost via TKO at 4:38 of round one.

Once again, the contest between the two ended in controversy as the doctor stopped the fight between rounds two and three due to a cut suffered by Spiritwolf, giving Žaromskis the TKO win.

Zaromskis then faced Canadian contender Nordine Taleb at Bellator 74 in the first round of the new Welterweight Tournament on September 28, 2012, in Atlantic City, New Jersey.

[9] However, Žaromskis was pulled from the bout to fight at another date, as a result, Parisyan faced Fernando Gonzalez.

[12] Marius won the fight after Andrzej broke his leg on a checked kick, rendering him unable to continue.
