The General Junta of the Principality of Asturias is the devolved, unicameral legislature of the autonomous community of Asturias, having legislative power in regional matters as defined by the Spanish Constitution and the Asturian Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.

[1] Voting for the General Junta is on the basis of universal suffrage, which comprises all nationals over 18 years of age, registered in Asturias and in full enjoyment of their political rights.

The 45 members of the General Junta of the Principality of Asturias are elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which includes blank ballots—being applied in each constituency.

[1][2][4] The president has the prerogative to dissolve the General Junta and call a snap election, provided that no motion of no confidence is in process, no nationwide election is due and some time requirements are met: namely, that dissolution does not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor before one year has elapsed since a previous dissolution under this procedure.
