Aquilonis (Latin "of the North Wind") is a classical and choral studio album by the Swedish trio Trio Mediæval recorded in June 2014 and released on the ECM New Series November that same year.

On this album the trio sings Icelandic chant and Italian sacred songs, with performing custom arrangements from old Norwegian folk melodies.

The trio also sings some 15th-century English carols, as well as contemporary works by Anders Jormin, William Brooks and Andrew Smith.

"[2] In The New York Times' Classical Top Music Recordings of 2014, James R. Oestreich says that "So varied are the sources that it is hard to find a theme or even a common thread.

But the enchanting vocal style and sonority that the female trio has evolved unifies the whole beautifully.
