The fast-food brand has been credited by the Cannes Lions for placing creativity at the heart of its advertising and communications. The award is awarded to brands that "inspire innovative marketing of their products worldwide" and which instil creativity in their agencies.
The trophy will be presented to McDonald’s senior vice-president and global chief brand officer Steve Easterbrook on Saturday 21 June in Cannes.
Philip Thomas, the Festival’s chief executive, said: "McDonald’s and its agencies have taken creative risks to produce meaningful work, and they see award-winning content earning higher returns – a success story that will, we hope, inspire other brands."
Easterbrook added: "McDonald’s is honoured to be named Creative Marketer of the Year.
"This award recognises the enduring and inspiring relationships we have with our agencies around the world. It’s a nod to our creative heritage and the power of the brand to connect with customers around the world with a local accent."
McDonald’s won its first Cannes Lion award in 1979 - a gold for TV work - and has since won in various categories including Creative Effectiveness and Mobile.
Last year's Creative Marketer of the Year award went to Coca-Cola.
