Sea Hero Quest is a mobile game which contributes to research on dementia. It was designed by British game company Glitchers in 2016 in association with Alzheimer's Research UK, University College London and the University of East Anglia and with funding from Deutsche Telekom.

The game is designed to help researchers to understand the mental process of 3D navigation, which is one of the first skills lost in dementia. It was hoped that a large number of people would play the game, thus contributing much more data than could easily be obtained in a laboratory experiment.

The plot of the game involves a sea journey taken by a son in a quest to recover the memories his father has lost to dementia. There are three sections: navigation, shooting flares to test orientation, and chasing creatures. Each has been "carefully crafted to be as fun and exciting as it is scientifically valid".

It was named "App of the week" by BT. It won nine Cannes Lions at the 2016 International Festival of Creativity. By February 2017, the game had been downloaded 2.7 million times. In August 2017, Sea Hero Quest came in a virtual reality edition.
