The Creative Mackintosh Festival begins today, and incorporates a range of events including an exhibition of his unbuilt designs at The Lighthouse in Glasgow.
MSP Humza Yousaf opened the festival at a ceremony also attended by Bailie Liz Cameron, Glasgow City Council's executive member for business and the economy; and Mackintosh Heritage Group chairwoman Caroline Barr.
Ms Barr said: "Mackintosh and his fellow Glasgow artists started a movement that rippled out across the world.
"Sometimes we take our homegrown talent for granted, but now that we are starting an annual festival to celebrate his legacy we hope everyone will be able to find something exciting, inspiring and enjoyable."
The inaugural festival runs until October 28.
