The 8,000-capacity event will see acts performing in a big top-style tent at the city's recently refurbished Northern Meeting Park on 28 March.
The programme includes blues artists and bands from across the world, including Grammy Award-nominated, Memphis-based Southern Avenue as well as UK award-winning singer Alice Armstrong and Chicago's West Weston's Bluesonics.
The festival is being supported by the Inverness Common Good Fund and could become an annual event.
