The Avedis Zildjian Company, simply known as Zildjian, is an Armenian-American musical instrument manufacturer and the largest cymbal and drumstick maker in the world. 

The company was founded in Constantinople (present-day Istanbul, Turkey) by Avedis Zildjian in 1623, and is now based in Norwell, Massachusetts.

Zildjian is one of the oldest manufacturers of musical instruments in the world. Zildjian sells cymbals, drumsticks, percussion mallets and other drum accessories under the Zildjian, Vic Firth and Balter Mallet brands.

The first Zildjian cymbals were created in 1618 by Avedis Zildjian, an Armenian metalsmith and alchemist. Like his father, who was also a metalsmith, he worked for the court of the Sultan of the Ottoman Empire in Constantinople. He made an alloy of tin, copper, and silver into a sheet of metal, which could make musical sounds without shattering.
