Alefoso Yalayalatabua (22 January 1977 – 18 July 2020) was a Fijian rugby union player.
Yalayalatabua was first capped for Fiji, on 19 May 2007, aged 30, in a 3-8 loss to Samoa.
He was in his country's squad at the 2007 Rugby World Cup finals, playing a single game, in the 12-55 loss to Australia.
His ties to the Fijian military hindered his international career because of New Zealand and Australia's ban on the Fiji military, which meant he would not be able to compete at the 2011 Rugby World Cup.
