The legislative districts of Ambos Camarines were the representations of the historical province of Ambos Camarines in the various national legislatures of the Philippines until 1919.
The undivided province's representation encompassed what the present-day provinces of Camarines Norte and Camarines Sur, and the independent component city of Naga.
Ambos Camarines was initially represented in the lower house of the Philippine Legislature through three assembly districts.
When seats for the upper house of the Philippine Legislature were elected from territory-based districts between 1916 and 1935, the province (and its successor provinces of Camarines Norte and Camarines Sur) formed part of the sixth senatorial district which elected two out of the 24-member Senate.
