Gyumri is an urban municipal community and the second largest city in Armenia, serving as the administrative centre of Shirak Province in the northwestern part of the country. By the end of the 19th century, when the city was known as Alexandropol, it was one of the largest cities of Russian-ruled Eastern Armenia with a population similar to that of Yerevan. It was renamed to Leninakan during the Soviet period. The city's population grew above 200,000 prior to the 1988 Spitak earthquake, when it was devastated. As of the 2011 census, the city had a population of 121,976, down from 150,917 reported at the 2001 census.

Gyumri is the seat of the Diocese of Shirak of the Armenian Apostolic Church.

Gyumri is home to many prominent museums of Armenia, including the House-Museums of sculptor Sergey Merkurov, poets Avetik Isahakyan and Hovhannes Shiraz, and actor Mher Mkrtchyan. The Aslamazyan Sisters Gallery, built in the 1880s, is home to more than 700 drawings, paintings and other works of the Aslamazyan sisters who were the Soviet-era artists. The Dzitoghtsyan Museum of Social Life and National Architecture of Gyumri is an old mansion, housing collections related to both history and the everyday-life of Gyumri, as well as paintings and other works of art.

Throughout centuries, Kumayri-Gyumri was labelled as the "city of crafts and arts", being famous for its schools, theaters and gusans.

In 1865, an amateur theatre group in Gyumri performed H. Karinyan's "Shushanik". In 1912, Gyumri was home to the first opera show ever staged in Armenia, when composer Armen Tigranian presented Anoush to the public in Alexandropol. In 1923, the first Armenian opera theatre was opened in Gyumri (where the first ballet performance in Armenia took place in 1924), while the Vardan Ajemian State Drama Theatre was founded in 1928. Prominent directors Ruben Simonov and Vardan Ajemian, actors Mher Mkrtchyan, Azat Sherents and Varduhi Varderesyan worked in theatre. The theatre's new building was opened in 1972. The artistic director is Nikolay Tsaturyan. Gyumri is known for its 19th-century architecture and urban constructions.

The first printing house of Gyumri was founded in 1876 by G. Sanoyan and operated until 1918. It published literary works (including Avetik Isahakyan's first book), calendars, textbooks. Another printing house, Ayg (founded 1892), published historical books and the first periodical of Gyumri, Akhuryan.
