Riptide is a ukulele line produced by Boulder Creek Guitars, a California-based instrument maker. The series is built around a dual-port body design, with one sound hole in the upper bout of the soundboard and a second port on the side facing the player, intended to project tone outward to a listener while giving the performer a clearer monitor of their own playing.

The Riptide catalog spans soprano, concert, tenor, and baritone sizes, with both acoustic and acoustic-electric configurations. Models such as the UC-5NG concert ukulele use a solid mahogany top with mahogany back and sides and a rosewood fingerboard, while the Spruce & Rosewood series pairs a solid spruce top with laminated rosewood. Acoustic-electric variants ship with onboard preamps and tuners, and many models are offered in both natural gloss and satin finishes alongside finishes like sea foam green.

Within the ukulele community, Riptide instruments are positioned in the mid-priced segment and are most associated with the dual-port construction borrowed from Boulder Creek's larger guitar designs. Reviews and forum discussions on sites such as Ukulele Underground and Ukulele Hunt focus on the side-port projection, build consistency, and tone of the mahogany and spruce-topped models.
