Mary, Mungo and Midge is a British animated children's television series, created by John Ryan and produced by the BBC in 1969.

The show featured the adventures of a girl called Mary, her dog Mungo, and her pet mouse Midge, who lived in a tower block in a busy town. BBC newsreader Richard Baker narrated the episodes, with John Ryan's daughter Isabel playing Mary. The theme tune and other music for the series was provided by Johnny Pearson.

This show was one of the first children's shows in the UK to reflect urban living. The programme showed Mary having adventures in a busy town, as opposed to in a wood, forest or other rural setting. The two featured animals were likely to be familiar to town dwellers, as opposed to the array of talking wildlife usually seen in children's television.

In each episode, the three of them would descend in the lift from their flat in the tower block. After their adventures they would return home, Midge would press the button for the lift back to the correct floor, by standing on Mungo's nose.

Mary, Mungo and Midge was a production of John Ryan Studios, who also produced the earlier Captain Pugwash and the later Sir Prancelot cartoons, both with a similar drawing style.
