João de Lisboa

João de Lisboa (c.1470 – 1525) 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's 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 (ca. 1550?) Portuguese nautical atlas.

He died in 1525 while traveling in the Indian Ocean.
