Johanna Hård née Jungberg (3 December 1789 – 12 March 1851), was a Swedish pirate. She was the daughter of farmer tenant Sven Haraldsson Jungberg (1736-1830) and Anna Britta Nilsdotter (1761-1825) in Hisingen in Gothenburg. In 1813, she married the book keeper Fredrik Hård (1776-1817). As widow, she lived on Vrångö. She had difficulty in supporting herself as a widow, and was once arrested for smuggling after having sailed to Copenhagen and sold textiles against the custom regulations. She was also, in 1822, put on trial accused of having murdered her newborn child, but freed after an investigation had proved the child to have been born dead.
