The Surrey theme park is seeking support from an agency to develop a 'pre-awareness' campaign for the launch of the 2013 season.
The aim is to reinforce the park's position as 'the choice for thrill-seekers and "up-for-it" families'.
The hunt follows the launch of The Swarm rollercoaster in March, which is expected to be a focus of the agency's work.
The appointed agency will be required to develop a 12-month plan including tactical media opportunities.
Pitches will be held at the end of next month.
Thorpe Park employed House PR as its retained agency to handle consumer publicity in 2011. The agency managed the launch of the Storm Surge ride.
