Franklin and the Turtle Lake Treasure (Franklin et le trésor du lac in France and Benjamin et le Trésor du lac in Canadian French) is a children's animated adventure drama film which was released on September 6, 2006 direct-to-video, based on the TV series Franklin. The first Franklin film shown in theaters in Canada and France, it was the last production in the Franklin series to be traditionally animated.

The film centres around Franklin's granny falling ill during a visit from Franklin's Aunt Lucy, an archaeologist. Aunt Lucy knows about a special talisman that may cure the illness and joins Franklin on a quest to find it, with his friends Bear, Beaver and Snail. They are also accompanied by Aunt Lucy's goddaughter, Samantha (Sam), whose personality clashes with Franklin's.

The film, released to direct-to-video in the United States by HBO, has had occasional TV airings on the Nick Jr. Channel. Writer John van Bruggen said, "This film will take Franklin on a much greater adventure than any of the past Franklin films, including Franklin and the Green Knight." The film, written by van Bruggen and directed by Dominique Monfrey, was distributed by Mars Distribution. StudioCanal distributed it internationally. It also had the working titles Franklin and the Secret Talisman and Franklin and Granny's Secret.

The film was the finale of the 1997 series, since no new episodes were produced after its release. It was Patricia Gage's final performance before her death in 2010.
