John V of Saxe-Lauenburg (also numbered John IV; 18 July 1439 – 15 August 1507) was the eldest son of Duke Bernard II of Saxe-Lauenburg and Adelheid of Pomerania-Stolp (*1410 – after 1445*), daughter of Duke Bogislaus VIII of Pomerania-Stolp. He succeeded his father in 1463 as duke of Saxe-Lauenburg.
After a fire John V reconstructed Saxe-Lauenburg's residential castle in Lauenburg upon Elbe, started in 1180–1182 by Duke Bernard I.
In 1481 John V redeemed Saxe-Lauenburg's exclave Land of Hadeln, which had been pawned to Hamburg as security for a credit of 3,000 Rhenish guilders since 1407. John V then made his son and heir apparent, Magnus, vicegerent of Hadeln, and finally regent as of 1498.
Having advanced to regent Magnus, who in 1484 had failed to conquer the rich Land of Wursten, a de facto autonomous region of free Frisian peasants in a North Sea marsh at the Weser estuary, won his father and Henry IV the Elder of Brunswick and Lunenburg, Prince of Wolfenbüttel on 24 November 1498 as allies in a second attempt to conquer Wursten. However, on 9 September 1499 the pre-emptive feud of the joint forces of Wursten, the Prince-Archbishopric of Bremen, Ditmarsh, the cities of Bremen, Buxtehude, Hamburg, and Stade against John V and Magnus turned the latter's campaign into an adventure involving heavy losses. By early December 1499 Prince-Archbishop Johann Rode of Bremen converted Henry IV to their column so that Magnus lacked support.
