The Red Army invasion of Azerbaijan, also known as the Sovietization or Soviet invasion of Azerbaijan, was a military campaign carried out by the 11th Army of Soviet Russia from 27 April to 11 May 1920 to install a new Soviet government in the Azerbaijan Democratic Republic, a former territory of the Russian Empire. The invasion coincided with the anti-government insurrection staged by the local Azerbaijani Bolsheviks in the capital Baku.

By early 1920, Soviet Russia desperately needed oil supplies from Baku. On 17 March 1920, Vladimir Lenin sent the following telegraph to the Revolutionary Military Council on the Caucasus Front:

We absolutely must take Baku. Direct all your efforts to this end, but it is necessary to remain strictly diplomatic in your statements and to ensure to a maximum extent a solid preparation for the local Soviet power. Same applies to Georgia, although in this case I advise you to be even more careful.

In January 1920, Mikhail Tukhachevsky, who arrived to Petrovsk-Port (present-day Makhachkala) along with the member of the Revolutionary Military Council, Sergo Ordjonikidze, was appointed as the commander Red Army's Caucasus district. On 21 April 1920, Tukhachevsky issued the following directive for the 11th Red Army and the Volga-Caspian military flotilla to initiative an offensive towards Baku:

Azerbaijan's main forces are busy on the western side of the country. According to our intelligence, only minor Azerbaijani force is defending the station of Yalama—Baku. In accordance with received directives, I order:

1. For the commander of 11th Army to cross the border Azerbaijan on April 27 and, in a quick offensive, to take control of the Baku province. Yalama—Baku operation to be concluded within 5 days. The cavalry units must be sent to take control of the Transcaucasian railroad around Kurdamir.

2. By the time, when 11th Army approaches the Absheron Peninsula, commander of the [Caspian] flotilla, Raskolnikov, to ensure landing of a small unit around the Alat station. This unit shall take orders from the commander of 11th Army. Make a quick raid to take control of Baku using all of the tanker fleet, prevent any damage to the oil fields
