Dyatkovo (Russian: Дя́тьково, [ˈdʲætʲ.kə.və]) is a town and the administrative center of Dyatkovsky District in Bryansk Oblast, Russia.

In 1790, in a forest near Dyatkovo, Marya Maltsova built the now famous glass and crystal factory, the quality of products of which was comparable to that of the plant in Gus.

In 1798, the ownership of the company passed to Ivan Akimovich Maltsov, who created an entire industrial empire centered in Dyatkovo.

By then, 100,000 people were employed by Maltsov's factories, which had their own currency, police force, and a 202-verst (215 km; 134 mi) long railway.

In 2003, new Dyatkovo church was built in honor of the icon Neopalimaya Kupina (Неопалимая купина, "Burning Bush").
