Bob the Builder, also known simply as Bob, is the titular protagonist of the British animated programme of the same name. He is a general contractor with his own construction yard in Bobsville, Sunflower Valley, Fixham Harbour, or Spring City depending on the programme.

Bob the Builder is a British animated children's television series created by Keith Chapman for HIT Entertainment and Hot Animation. The series follows the adventures of Bob, a general contractor, specialising in masonry, along with his colleague Wendy, various neighbours, and friends, and equipment, and their gang of anthropomorphised work-vehicles, Scoop, Muck, Dizzy, Roley, Lofty and many others. The series ran from 12 April 1999 to 31 December 2011 in the United Kingdom through the CBBC strand and later CBeebies. The series originally used stop-motion from 1999 to 2009, but later used CGI animation starting with the spin-off series Ready, Steady, Build! (2010-2011). The British proprietors of Bob the Builder and Thomas & Friends sold the enterprise in 2011 to US toy-maker Mattel for $680 million.
