Johannes Alanus was an English composer. He wrote the motet Sub arturo plebs/Fons citharizancium/In omnem terram. Also attributed to him are the songs "Min frow, min frow" and "Min herze wil all zit frowen pflegen", both lieds, and "S'en vos por moy pitié ne truis", a virelai. O amicus/Precursoris, attributed simply to "Johannes", may be the work of the same composer.
