Arisia is a Boston-area, volunteer-run science fiction convention, named for a planet in the Lensman novels by E. E. "Doc" Smith. The name was chosen in response to an older Boston-area con, Boskone, which took the typical ending for a convention—con—and then altered the spelling to match the name of an organization in the Lensmen books. Arisia was first held in 1990, and its attendance has grown from 842 to over 4,000. Arisias 2000–2006 were held at the Park Plaza Hotel in downtown Boston, and Arisias 2007–2010 were held at the Hyatt Regency in Cambridge, Massachusetts. From 2011 to 2018, the convention was held at the Westin Boston Waterfront. In 2019, Arisia moved back to the Boston Park Plaza Hotel temporarily as a result of a strike at Boston-area Marriott properties, including the Westin. Later that year after a legal dispute, Arisia agreed to return to the Westin for the 2020 convention, and also signed a contract for the Westin to host through 2023. Due to the COVID-19 pandemic, the convention was held online only in 2021 and 2022, returning to the renamed Westin Boston Seaport District in 2023 and 2024. More information...
