Kanutus Johannis (first half of the 15th century – 28 August 1496) was a Swedish Franciscan friar, writer and book collector. Coming from a burgher family, he rose within the ranks of the Greyfriars Monastery in Stockholm and eventually became its leader. He wrote in Latin and produced a small variety of works in a style which has been called "unremarkable" but which remains a testament of medieval Swedish literature written in Latin. His book collection, acquired partially by purchases abroad, was donated to the monastery and partially survives within the collections of Uppsala University Library.
