Hey Duggee is a British pre-school children's animated television series aimed at two to five-year-olds. Created by Grant Orchard, it is produced by Studio AKA, in association with BBC Studios (formerly BBC Worldwide). The show is narrated by Alexander Armstrong.

The programme's characters are talking anthropomorphic animals, with Duggee communicating in woofs. The episodes are based around The Squirrel Club, an activity club for children that Duggee leads. The children – the club's Squirrels – take part in all kinds of activities, have adventures and earn badges for their accomplishments. Each episode shows the Squirrels completing an activity or adventure relating to a badge that they earn at the end of each episode. There is no set formula for every episode, with many referencing or parodying pop culture.

Hey Duggee has four series. It was first shown on 17 December 2014, and officially premiered on 12 January 2015. The BBC and Studio AKA produced a second series in early 2016, with the first episode airing in the United Kingdom on 26 September 2016. A third series was commissioned in October 2017, with the first episode due to be broadcast in Autumn 2018, but was pushed back to 4 March 2019.
