RNAS Hornsea Mere,, was a Royal Naval Air Service seaplane base located on Hornsea Mere, in the East Riding of Yorkshire, England. The mere was used for seaplanes because it was close to the sea and because its still water made it easier to launch the planes. Initially used as a relief site, the base became a full station in 1918, and was vacated in 1919. Many of the original buildings and earthworks survive.
