Jason Lewis FRGS (born 13 September 1967) is an English author, explorer and sustainability campaigner credited with being the first person to circumnavigate the globe by human power. He is also the first person to cross North America on inline skates (1996), and the first to cross the Pacific Ocean by pedal power (2000). Together with Stevie Smith, Lewis completed the first crossing of the Atlantic Ocean from mainland Europe to North America by human power (1995).

Lewis set off with friend and fellow adventurer Stevie Smith from Greenwich, London on 12 July 1994, to complete the world's first human-powered circumnavigation, and the two dubbed the journey Expedition 360. By July 2007, Lewis had travelled over 60,000 km (37,000 mi). He successfully ended his 4,833-day expedition on 6 October 2007, having travelled 74,842 km (46,505 mi).

In mid-1994, Lewis and Smith mountain-biked 2,700 kilometres (1,700 mi) through France, Spain and Portugal to the port of Lagos, Portugal. Departing on 13 October 1994, Lewis and Smith then pedaled 111 consecutive days and 7,200 kilometres (4,500 mi) across the Atlantic Ocean from Portugal to Miami, Florida in a wooden pedal-powered boat named Moksha.

Lewis then rollerbladed thousands of miles across North America. He was struck by a drunk driver in Pueblo, Colorado, and spent nine months recovering from two broken legs. He finished the North American expedition leg in 1996. In 1998 and 1999, Lewis and Smith spent 53 days pedaling Moksha across the Pacific Ocean from San Francisco, California to Hilo, Hawaii, where Smith ended his journey. In four days, Lewis and a small group of supporters hiked the 80 miles across Hawaii.

After 73 days of solo pedaling Moksha across the doldrums, Lewis completed the Pacific Ocean crossing from Hawaii to the island atoll of Tarawa. In May 2000, he was accompanied by Moksha's builder, Chris Tipper, to pedal the 1,300-mile stretch from Tarawa to the Solomon Islands. With the help of friend and expedition supporter April Abril, Lewis then pedaled Moksha 1,450 miles for 32 days across the Coral Sea to Australia. In 2001, Lewis and a group of supporters spent 88 days cycling 3,500 miles across the Australian outback, starting near Cooktown, Queensland, and finishing in the port city of Darwin, Northern Territory.

After spending many years raising funds to continue Expedition 360, Lewis was reunited with Moksha in 2005. He and expedition supporter Lourdes Arango pedaled 450 nautical miles from Darwin to Dili, East Timor.

Throughout 2005, Lewis kayaked thousands of miles through the Indonesian archipelago from East Timor to Singapore. In 2006, he biked from Singapore to the Himalayas, and biked and hiked through the Himalayas to the port of Mumbai. Covering 2,000 nautical miles in 46 days during early 2007, Lewis and friend Sher Dhillon pedaled Moksha from Mumbai, India, crossing the Arabian Sea to Djibouti.^{[citation needed]}

Lewis then planned to travel through Ethiopia, Sudan, Egypt, and the Middle East before reaching Europe – encountering a problem at the Sudan-Egypt border. The Egyptian authorities would not let him pass through their waters, and when his visa for Sudan ran out he was left with an "impossible decision".^{[citation needed]} He attempted to kayak across Lake Nasser to Abu Simbel but was arrested on suspicion of spying. He was released, but Egyptian authorities forbade him from cycling the 178-mile journey to Aswan. He completed this section illegally by riding partly at night. During his journey through Sudan he encountered actors Ewan McGregor and Charley Boorman who were travelling south as part of their Long Way Down motorbike trip.
