This is a list of frigate classes of the Royal Navy of the United Kingdom (and the individual ships composed within those classes) in chronological order from the formal creation of the Royal Navy following the Restoration in 1660. Where the word 'class' or 'group' is not shown, the vessel was a 'one-off' design with just that vessel completed to the design. The list excludes vessels captured from other navies and added to the Royal Navy.

All frigates built for the Royal Navy up to 1877 (when the Admiralty re-categorised all frigates and corvettes as "cruisers") are listed below. The term "frigate" was resuscitated in World War II and subsequent classes are listed at the end of this article, but the individual ships within those classes are not listed in this article.

The initial meaning of frigate in English/British naval service was a fast sailing warship, usually with a relatively low superstructure and a high length:breadth ratio—as distinct from the heavily armed but slow "great ships" with high fore- and after-castles. The name originated at the end of the 16th century, the first "frigats" being generally small, fast-sailing craft, in particular those employed by Flemish privateers based on Dunkirk and Flushing. Subsequently, the term was applied to any vessel with these characteristics, even to a third-rate or fourth-rate ship of the line.

In this list, the term is restricted to fifth rates and sixth rates which did not form part of the battlefleet (i.e. were not ships of the line); many of the earliest ships described as English frigates, such as Constant Warwick of 1645, were third-rate or fourth-rate ships of the line and thus are not listed below. As the Royal Navy was not officially created until 1660, vessels from the preceding (Commonwealth) era are only included where they survived past 1660. Prizes taken from enemy naval forces and added to the Royal Navy are also excluded.

Prior to 1626 when the rating system was established, these vessels were known as pinnaces. The vessels were considered too lightly armed and built to stand in the line of battle. Fifth rates were essentially two-decked vessels, with a demi-battery on the lower deck and a lesser number of guns of lesser power on the upper deck (as well as even smaller guns on the quarterdeck).

Sixth rates were single-decked vessels, with a battery on the (single) gun deck, and usually some lesser guns on the quarterdeck.

Charles Galley was an early galley-frigate with a bank of sweeps above the waterline, the last of these types (Royal Anne Galley) being launched in 1709.

For ships before the 1745 Establishment, the term 'class' is inappropriate as individual design was left up to the master shipwright in each Royal dockyard. For other vessels, the Surveyor of the Navy produced a common design for ships which were to be built under a commercial contract rather than in a Royal Dockyard. Consequently, the term 'group' is used as more applicable for ships built to similar specifications (and to the same principal dimensions) but to varying designs.
