Princess Gwenevere and the Jewel Riders, also known outside of North America as Starla & the Jewel Riders and sometimes spelled as the more traditionally Arthurian "Guinevere", is an American fantasy animated television series aimed at a pre-teen girl audience and produced by Bohbot Entertainment in association with Hong Ying Animation Company Limited. It was internationally syndicated by Bohbot on their syndicated Amazin' Adventures block, where it originally ran from 1995 to 1996, with two seasons and twenty-six episodes.

The series follows the titular protagonist, Princess Gwenevere of Avalon, and her fellow Jewel Riders, Fallon and Tamara, in their quest to find the seven lost enchanted jewels and stop the evil sorceress Lady Kale from conquering Avalon. In the second season, the Jewel Riders gain new powers and fight against Kale and new enemy Morgana as they search for more magical jewels in order to rescue their banished mentor, Merlin, and restore harmony in magic.

The series bears similarities to The Adventures of the Galaxy Rangers, as they had the same creator and director, Robert Mandell, as well as some writers in common, notably Christopher Rowley. The series was initially planned to be an adaptation of Dragonriders of Pern and came in the wake of Bohbot's earlier take on the Arthurian legends, King Arthur and the Knights of Justice.

In the 2000s, the series was rebooted as the novel series Avalon: Web of Magic. In 2023, a sequel comic was announced by Mad Cave Studios. Its first volume was released in May 2024.
