A "ring of bells" is the name bell ringers give to a set of bells hung for English full circle ringing. The term "peal of bells" is often used, though peal also refers to a change ringing performance of more than about 5,000 changes.

By ringing a bell in a full circle, it was found in the early 17th century that the speed of the bell could be easily altered and the interval between successive soundings (strikes) of the bell could be accurately controlled. A set of bells rung in this manner can be made to strike in different sequences. This ability to control the speed of bells soon led to the development of change ringing where the striking sequence of the bells is changed to give variety and musicality to the sound.

The vast majority of "rings" are in church towers in the Anglican church in England and can be three to sixteen bells, though six and eight bell towers are the most common. They are tuned to the notes of a diatonic scale, and range from a few hundredweight (100 kg) up to a few tons (4,000 kg) in weight. They are most commonly associated with churches as a means of calling the congregation to worship, but there are a few rings in secular buildings. Smaller rings of bells, known as "mini-rings" have come recently into existence for training, demonstration or leisure purposes, with bells weighing just a few kilograms.
