The London Fancy is a extinct canary breed that has been revived. After more than 100 years, it became an officially recognized COM breed in 2023. Its history is closely linked with the Lizard canary. The breed originated in the London area and was popular between 1770 and 1860. By 1900, the breed had nearly disappeared due to inbreeding and crossing with other varieties.

Modern revival efforts began in 1997 with the New London Fancy Canary Club. The breakthrough came in 2004 when Piet Renders from the Netherlands bred the first modern London Fancy. The bird's key feature is melanin-free small feathers (head and body) contrasting with very dark wing and tail feathers. The ideal color is a rich golden yellow (intensive) or soft yellow (non-intensive) with black or very dark extremities.

Young birds resemble Lizard canaries; only after their first molt does the typical pattern appear – the melanin disappears from the body feathers while the wings remain dark. Breeding is still challenging: even two perfect parents can produce offspring with varying amounts of melanin spots. The breed is now shown annually in the UK and Netherlands, and the standard includes points for pattern, color, condition, and size (ideal length 13.5 cm).
