Henk de Velde (12 January 1949 – 3 November 2022) was a Dutch seafarer. He was especially known for his long solo-voyages around the world. Initially he worked for thirteen years in the merchant navy, from able-bodied seaman to captain. When he was 28 he chose definitively for ocean-sailing. In 1978, he started with its first voyage around the world, which would eventually take seven years. He made this voyage with his former wife until they separated in 1984. Their son Stefan Vairoa was born on Easter Island in 1981. In 1985, he returned to the Netherlands. In 1989, he left again for a nonstop circumnavigation with a 60-foot (18 meter) catamaran, called Alisun J&B, and it took him 158 days. He had to stop in New Zealand for repairs. His third voyage, in 1992, with a 60 ft (18 meter) catamaran called Zeeman, was viewed on Dutch TV in the so-called 5 O'clock Show.

In 1996, he departed with a 71-foot catamaran, called C1000 and sailed in 119 days non stop around the world. Officially he did not break the record because he did not sail under the rules of the WSSRC. He is still the only person in the world who sailed a catamaran nonstop single handed around the world. In 2001 de Velde started again, with a steel monohull yacht called Campina, this time using a totally new route, instead of west to east or east to west he wanted to sail the world north to south by passing the NE passage north of Siberia. It took him three and a half years. He had to winter near the village of Tiksi in Northern Siberia. Temperatures were between -35 and -60 °C. He stayed on board in the white desert of the Arctic Ocean. In 2004, he got the aid of a Russian nuclear icebreaker Vaigach. The rudders were demolished by heavy ice. In December 2004 he returned with his damaged vessel to the Netherlands. Henk de Velde has written seven books, all in Dutch. In all his writings he contemplates the
