This is an episode list for the British animated children's television series Bob the Builder, which premiered on in the United Kingdom (it airs CBBC between 1999 to 2001 and CBeebies between 2002 to 2011) and in the United States (it airs Nick Jr. between 2001 to 2003 and PBS Kids between 2005 to 2011).
The series finale aired on as a mini series titled The Big Dino Dig, which ended the original series after 18 series.
The series was centred around Bob and his crew's adventures in their new home of Sunflower Valley. Many new machines were introduced, and throughout the episodes Bob always tried to be eco-friendly. The show's intro begins with one of Bob's crew and one of other machines doing the job before Wendy and Bob wave good morning and begin their jobs. The show ends with Bob's crew going to sleep and Wendy and Bob waving good night before one of Bob's crew and one of other machines does the job.
The second spin-off is Bob the Builder: Ready, Steady, Build!. In June 2008, after production of Project: Build It wrapped up, it was announced that the series would be revamped for environmental CGI. The gang has now apparently moved to a place called Fixham Harbour and the show is now animated in CGI animation instead of the traditional stop-motion animation.
