Jonathan David Anthony Bowden (12 April 1962 – 29 March 2012) was an English political activist, orator, writer and artist. A member of the Conservative Party in the early 1990s, he later became involved in far-right organisations, including the British National Party (BNP). Bowden has been described as a "cult figure" amongst the far-right movement, even more than a decade after his death.

Bowden was born in Royal Tunbridge Wells in Kent, and attended Presentation College in Reading, Berkshire. He was an only child. His mother, Dorothy Bowden, suffered from severe mental illness.

In 1984 he completed one year of a Bachelor of Arts history degree course at Birkbeck, University of London, as a mature student, but left without graduating. He enrolled at Wolfson College, Cambridge, in 1988, but left after a few months. He became a lifelong friend of the novelist Bill Hopkins (1928–2011), one of the angry young men, during this time. Bowden was otherwise largely self-educated.

Bowden began his career as a member of the Conservative Party in the parliamentary constituency of Bethnal Green and Stepney. In 1990 he joined the Monday Club, a pressure group on the fringes of the party, and the following year made an unsuccessful bid to be elected onto the club's Executive Council. In 1991 he was appointed co-chairman, with Stuart Millson, of the club's media committee, and was also active in the Western Goals Institute. In 1992 Bowden was expelled from the Monday Club. (The Conservative Party disassociated itself from the Monday Club in 2001, and the club disbanded in 2024.)

Bowden and Millson co-founded the Revolutionary Conservative Caucus in November 1992 with the aim of introducing "abstract thought into the nether reaches of the Conservative and Unionist party". It published a quarterly journal entitled The Revolutionary Conservative Review. By the end of 1994 Millson and Bowden parted company and the group dissolved.

In 1993 Bowden published Right through the European Books Society. He was also reported to be a prominent figure in the creative milieu responsible for the emergence of the political magazine Right Now!.

Bowden then joined the Freedom Party; he was its treasurer for a short time, and subsequently was a member of the Bloomsbury Forum, alongside Adrian Davies.

In 2003 Bowden joined the BNP. He was appointed Cultural Officer, a position that was created by Nick Griffin, the party's leader at the time, to give Bowden an official role. In July 2007 Bowden resigned both his position and his membership after a dispute between him, Griffin and other individuals within the party. Although he gave speeches throughout England and Wales at local meetings for the BNP, he never re-joined the party, and cut all ties after the 2010 general election.
