List of ships of the line of Spain

This is a list of Spanish ships of the line (comprising the battlefleet) built or acquired during the period 1640-1854:
Those with 94 or more guns were three-deckers, while all the others listed were two-deckers. The Spanish term for ships of the line was navíos, but during the latter part of the Habsburg era (until 1700) ships continued to be designated as galeón. Those ships with secular names (e.g. royal, geographical or adjectival names) were additionally given an official religious name (or advocación) which appears below in parentheses following the secular name.

Until 1716 there was not one single Spanish Navy but several naval forces, of which the Armada del Mar Océano was the primary one but several other distinct forces existed. The Real Armada ("Royal Navy") was created by the newly-established Bourbon government in 1716, but the other armadas (in Spanish, the word "armada" is used for both "navy" and "fleet") endured for several years thereafter. During the early 1750s, the term Real Armada was replaced by Armada Española.
