Lewis Kristian Marnell (3 December 1982 – 18 January 2013) was a professional skateboarder from Melbourne, Australia who was Slam Magazine's 2008 "Skater of the Year". Marnell died in January 2013, following complications related to type 1 (juvenile) diabetes, a condition that was diagnosed when he was 10 years old. Numerous tributes were published following Marnell's death and his longtime skateboard deck sponsor, Almost Skateboards, continues to use the hashtag "#LewisMarnellForever"—on 15 and 29 July 2014, the company published the hashtag with 2006 video footage of Marnell skateboarding in Japan.
