The 2017 Catalan independence referendum (Catalan: Referèndum sobre la independència de Catalunya de 2017) is a independence referendum that occurred in Catalonia on 1 October 2017.^[1] Political parties that do not want independence will boycott the referendum.

The referendum is illegal according to the Spanish constitution.^[2] The Constitutional Court of Spain suspended the referendum on 7 September 2017. The Catalonia government said the court order was not valid, and got support from 750 of 948 municipalities.^[3][4] This led to the 2017 Spanish constitutional crisis.

The Government of Spain opposes Catalan independence.^[5] However, the Catalan government says it has the right to independence. Catalonia has not gotten any international support.
