"I am honoured to lead the Kings XI Punjab squad this year. I would like to thank the franchise, promoters, management and all the team members for the confidence they have in me.
"Kings XI have assembled an exciting squad with a good mixture of youth and experience and I am really looking forward to the opportunity that lies ahead," Miller said on Tuesday.
He is associated with Kings XI since season 4 of the cash-rich Twenty20 tournament.
Kings XI coach Sanjay Bangar expressed confidence in Miller's potential as a leader.
"I have watched David grow as a player. He has displayed outstanding batting abilities and a cool temperament in many high-pressure situations. I am confident in his potential to lead the boys this season," Bangar said.
