Vocaloid is a singing voice synthesizer technology developed by Yamaha, along with the products built upon it. By inputting a melody and lyrics, users can synthesize a singing voice based on prerecorded human vocal samples. Various companies licensed by Yamaha produce their own vocal libraries, which are combined with Yamaha's software and sold as products. Many of these voice banks are associated with a character design, and such characters are themselves often referred to as "Vocaloids" or "virtual singers."

Songs created using Vocaloid are commonly called "Vocaloid songs," and the composers or creators who make them are known as "Vocaloid producers." Using a piano-roll style interface, users can adjust pitch, pronunciation, dynamics, and effects such as vibrato in detail, allowing expressive vocal performances to be created without an actual singer. In recent years, the term "Vocaloid" has come to refer not only to the software itself but also to the broader body of songs and the surrounding music culture, with a wide variety of creators continuing to produce diverse works using the technology.
