Jakers! The Adventures of Piggley Winks, or Jakers in Europe, is an animated children's television series created and developed by Mike Young, Liz Young, Sindy McKay-Swerdlove and John Over based on an original idea by Denise Fitzpatrick and produced by Entara in association with Mike Young Productions with the animation provided by Crest Communications.

The series ran for three seasons and 52 episodes total from September 7, 2003, to January 23, 2007, with reruns airing through August 31, 2008. Reruns aired on the Qubo television network from June 30, 2012 to March 26, 2017.

The show chronicles the boyhood adventures of Piggley Winks, an anthropomorphic pig from Ireland, and how he relates these stories to his grandchildren as a grandfather in the modern day. Many of the stories takes place on the Winks family's farm, Raloo Farm, located in the village of Tara. The word "jakers" was originally an euphemism for "Jesus" in much of Ireland during the 1950s and 1960s, and was an exclamation of surprise, delight, dismay, or alarm. Piggley and his father exclusively use it to express their delight when they discover something on their adventures. Notably, the show contains voiceover work by the actors Joan Rivers and Mel Brooks.
