The 27th Artillery Brigade named after Kish otaman Petro Kalnyshevskyi () is a brigade of the Ukrainian Ground Forces.
The 27th Artillery Brigade traces its origins to 2008, when it was established in Sumy following the disbandment of the Sumy Institute of Missile and Artillery Troops. Initially formed as the 27th Rocket Artillery Regiment, the unit was officially presented with its battle flag on December 5, 2008. In early 2015, the regiment underwent reorganization and expansion, transforming into the 27th Rocket Artillery Brigade.
The brigade first saw action in the war in Donbas in July 2014, where it carried out fire missions across the Luhansk and Donetsk regions.
Over time, the unit transitioned from Soviet BM-27 Uragan to more advanced equipment, becoming one of the first Ukrainian formations to operate HIMARS multiple launch rocket systems during Russias invasion. During Ukraine's 2023 counteroffensive, the brigade fought on the Zaporizhzhia front. The following year, in 2024, it also contributed to Ukraine's offensive operations in the Kursk region.
On April 13, 2025, its commander, Colonel Yurii Yula, was killed in a Russian Iskander missile strike on Sumy. Later that same year, the brigade underwent another transformation, reorganizing into an Artillery Brigade.
As of 2025, the brigade's structure was as following:
