Bridge, who takes up her role in January, will lead a new directorate that includes marketing and fundraising in addition to the comms function.
She said: "With an ageing population, raising awareness and public support for the extraordinary work Marie Curie does in caring for those living with terminal illnesses and their families has never been more important. I am delighted to be joining such a vital organisation and helping Marie Curie extend the reach, care and support it provides."
In a sign of the continued professionalisation of the charity comms world, Bridge comes from a largely commercial background.
She joins the charity from Mothercare, where she was its global brand and marketing director.
Before this, Bridge was director of comms for Save the Children and was previously marketing comms director for Marks & Spencer.
Bridge has also had stints at Publicis, United Biscuits and Unilever.
At Marks & Spencer and Save the Children Bridge led on major brand campaigns ‘Your M&S’ and ‘No Child Born to Die’ respectively.
Dr Jane Collins, chief executive of Marie Curie, said: "Jude will be joining at an extremely important point in Marie Curie's history. Bringing all our public-facing activity under one directorate is key to ensuring we successfully deliver our bold and ambitious strategy. Jude's marketing skills and general management experience, gained in both commercial and charitable sectors, will be of immense benefit to Marie Curie."
