Hamleys is the oldest and largest toy shop in the world and one of the world's best-known retailers of toys. Founded by William Hamley as "Noahs Ark" in High Holborn, London, in 1760, it moved to its current site on Regent Street in 1881. This flagship store is set over seven floors, with more than 50,000 lines of toys on sale. It is considered one of the city's prominent tourist attractions, receiving around five million visitors each year. The chain has ten other outlets in the United Kingdom and also has more than 60 franchises worldwide.

It is named after William Hamley, who founded a toy shop called "Noah's Ark" at No. 231 High Holborn, London, in 1760. Ownership of the shop passed through the family, and by the time it was operated by Hamley's grandsons in 1837, the store had become famous, counting royalty and nobility among its customers.

A branch at No. 200 Regent Street was opened in 1881; the original High Holborn shop was destroyed by fire in 1901 and was subsequently relocated to Nos. 86–87 High Holborn. The Regent Street branch later expanded to Nos. 188-196.
