Bridges's degu (Octodon bridgesii) is a species of rodent in the family Octodontidae.

[3] The species was named after Thomas Bridges.

[4] Ricardo Ojeda's degu (O. ricardojedai), which is found in Argentina and Chile, was formerly considered a population of O. bridgesii, but was described as a distinct species in 2020.

[7] The species is less widely distributed in Chile than the common degu and inhabits rocky, forested areas[7] and some open farmland,[3] although it is far less well adapted for digging[6] but does have some climbing ability.

[8] Deforestation may be contributing to the decline of this species.
