João de Lisboa was a Portuguese explorer. He is known to have sailed together with Tristão da Cunha, and to have explored Río de La Plata and possibly the San Matias Gulf, around 1511-12.
The Brazilian historian Francisco Adolfo de Varnhagen erroneously stated that he was in Ferdinand Magellan circumnavigation voyage.
He is the author of a Treatise on the Nautical Needle, dated 1514, which is extant in a later copy included in an undated Portuguese nautical atlas.
He died in 1525 while traveling in the Indian Ocean.
