Isoa Coalala Neivua (born 7 June 1978 in Mosimosi, Sigatoka, Fiji) is a Fijian rugby union player.

Playing in Fiji, he moved from Navosa to Nadroga in 2003 to get more chance of being spotted by for the national team.

A great showing in the Colonial Cup saw Neivua dubbed as the next Rupeni Caucau, but injury ruled him out of the Pacific Tri-Nations tournament.

His return to the Nadroga jersey came just in time for the knock-out stages of the Telecom Fiji Cup where he was instrumental in Nadro's semi-final win over Naitasiri.

On his unofficial Fiji debut against the NZ Divisional XV in 2004, he scored a try just six minutes after coming on as a substitute in the second half.
