Celtic players will wear black armbands in Miller's memory during their William Hill Scottish Cup match against Partick Thistle on Saturday.
Reports emerged in November that Miller had been battling pancreatic cancer and was receiving treatment in the United States, where he played for Wilmington Hammerheads.
Wilmington, who Miller played for in 2016, were the last of 12 clubs the Cork-born midfielder represented during a 16-year career that took him around the world.
He made his professional debut for Celtic in 2000 after coming through the youth ranks at Parkhead and helped them win the Scottish Premier League title in 2004.
He then moved south to Manchester United on a free transfer, making 22 appearances under Sir Alex Ferguson in two seasons - which included a spell on loan at Leeds - before joining Sunderland in 2006.
Miller was part of the Black Cats' squad that won promotion to the Premier League in 2007 but he was on the move again in 2009, this time to QPR.
A short spell at Loftus Road was followed by stints at Hibernian , Australian clubs Perth Glory, Brisbane Roar and Melbourne City, home-town club Cork City and, most recently, Wilmington.
Miller won 21 caps for the Republic of Ireland after making his debut in 2004.
