The Fabian Window is a stained-glass window depicting the founders of the Fabian Society, designed by George Bernard Shaw. The window was stolen from Beatrice Webb House in Dorking in 1978 and reappeared at Sotheby's in 2005. It was restored to display in the Shaw Library at the London School of Economics (LSE) in 2006 at a ceremony presided over by then-Prime Minister Tony Blair, emphasising New Labour's intellectual debt to the Fabians.

The Fabian Society is a British socialist organisation whose purpose is to advance the principles of social democracy and democratic socialism via gradualist and reformist effort in democracies, rather than by revolutionary overthrow. The Fabian Society was also historically related to radicalism, a left-wing liberal tradition.
