The British model and actress fronts the autumn 2017 and spring 2018 ad campaigns for the the French cosmetics brand.
The collaboration was announced on Instagram in a post that introduces the new campaign that celebrates individuality.
In a short clip, which was created on the set of campaign shootings in New York, Suki explained why she decided to work with the label.
'I'm incredibly excited to be representing the brand because I've been wearing Laura Mercier products my entire life,' she said in a statement.
'In fact, I started raiding my Mum's make-up bag for them when I was just a kid, so meeting Laura herself was a thrill.'
'Our brand has been embraced by a younger audience and we want to tell young women that we are speaking to them,' said Laura Mercier, the make-up artist and entrepreneur.
'There is so much happening in artistry today - from technique to using quality products - and we felt that it was essential to be represented by a young, talented, confident woman.'
Laura Mercier will debut three new products alongside the campaign: Caviar Stick Eye Colour Matte, launching in July, Flawless Fusion Ultra Longwear Foundation, launching in September, and Velour Extreme Matte Lipstick, which will launch in January.
