The 1999 Rugby League Tri-Nations series was contested by Australia, Great Britain and New Zealand in 1999.

After the Lions narrowly defeated the Queensland Cup premiers, Burleigh Bears, a poor crowd attended their match against Australia at Suncorp Stadium.

Fearing a similar attendance for the series final, the tournament organisers relocated the match to Ericsson Stadium.

With the Rugby League World Cup to be staged the following year, and tours of Great Britain by Australia in 2001 and 2003 and New Zealand in 2002, the Tri-nations was not held again until 2004.

As a curtain raiser to the final, New Zealand Māori played Great Britain.
