The University Royal Naval Units (URNU) (/ˈər.nuː/ UHR-noo, less commonly /ˈɜːr.nuː/ ERR-noo) (formerly Universities' Royal Naval Units) are Royal Navy training establishments who recruit Officer Cadets from a university or a number of universities, usually concentrated in one geographical area. There are 17 URNUs in the UK, with each URNU having land-based facilities near the universities they recruit from, with the exception of URNU Virtual, whose drill nights are conducted virtually.
