Gwendolyn "Gwen" Tennyson, occasionally known as Lucky Girl, is a fictional character that appears in Cartoon Network's Ben 10 franchise, created by Man of Action. The paternal first cousin and best friend of title protagonist Ben Tennyson, Gwen is a core member of Ben's team who frequently aids him in his various adventures to defeat villains and criminals and protect and save earth and the universe. A highly intelligent and strong martial artist, Gwen later develops magic abilities that are eventually revealed to be alien in nature, having inherited it from her alien paternal grandmother, Verdona.

Gwen was created for Ben 10 (2005–2008), in which she was voiced as a 10-year-old by Meagan Smith. Smith was replaced by Ashley Johnson, who voiced the teenage Gwen for the sequel series Ben 10: Alien Force, Ben 10: Ultimate Alien, and Ben 10: Omniverse, while Montserrat Hernandez voiced Gwen for the 2016 reboot. Tara Strong also briefly voiced a version of Gwen set in an alternate future from the original series.
