Canas de Senhorim is a civil parish in the municipality (concelho) of Nelas, in the central sub-region of Dão-Lafões in Portugal.

Canas de Senhorim was a municipality by the 19th century, when the parish of Carvalhal Redondo was annexed.

For a better part of the 20th century, Canas de Senhorim was known for its persistent fight to restore its municipal status.

A movement was formed to challenge Nelas's politicians authority, protesting through election boycotts, disruption of the rail service through the main town, and public demonstrations in Lisbon.

On 3 July 2003, the national assembly approved motion to restore the regions status, but President Jorge Sampaio vetoed the decree a month later, provoking general outrage.
