The five new Agatha Christie adaptations will include 'Labours of Hercules', 'Dead Man's Folly', 'The Big Four', 'Elephants Can Remember' and the Belgian detective's final case 'Curtain'.
David Suchet will reprise the title role, having first played the character in 1989. The British actor previously expressed his desire to film the entire Poirot canon.
"I'm more than delighted to be reprising my role as Poirot," he confirmed. "It's been my life's ambition to bring this amazing canon of works to completion on ITV."
ITV's director of drama commissioning Laura Mackie added: "Poirot is without doubt one of fiction's finest detectives and we're thrilled to welcome him back to ITV1 with his refined approach to crime-fighting.
"We're equally delighted that David has agreed to play him in the final Poirot films for the ITV1 audience and immensely privileged to be producing 'Curtain'."
It was previously rumoured that Poirot was to be axed by ITV, due to budget restrictions.
However, new film 'The Clocks' will air on ITV1 this Christmas, featuring Phil Daniels,
Jaime Winstone, Tom Burke, Lesley Sharp, Geoffrey Palmer, Beatie Edney and
the late Anna Massey opposite Suchet.
Production on the final five films will then begin in 2012.
