Queendom is the second album of the Japanese rock group Show-Ya. The album was released on 1 March 1986 in Japan.

Show-Ya's second album was recorded with less external pressure than their debut album Masquerade Show and presents only songs composed and arranged by the band. The album was again mixed at Abbey Road Studios in London by Haydn Bendall. The band shoot their first video clip for the single "Shidokenaku Emotion".

In this work the sound of the band is more identifiable and shows in many songs a powerful hard rock feel, with the strong interaction between keyboards and guitars that will become a characteristic feature of the band. However, Terada's romantic lyrics and the acerbic looks of the costumed musicians seem to pigeonhole this work as a pop-rock album, in the vein of Princess Princess similar products.

A Queendom is a monarchy, ruled by a queen rather than a king. A queendom is not simply a kingdom ruled by a queen (see kingdom of England, ruled by Elizabeth II). A queendom is a monarchy where the line of succession runs through the female line, rather than the male line. In many monarchies, the office of monarch is inherited though a set of rules which often either favor male heirs, as in England, or exclude females as heirs entirely, as in the Kingdom of France; a queendom, presumably dose the opposite.

This is, however, an extremely rare term as there has never been an official Queendom. Most Dictionaries reference to Queendoms only in passing, as a female counterpart in the definition of a Kingdom, if at all. The term has, however, seen limited use in fiction, as in The Queendom of Sol.

An album may be understood as a collection of recordings, released as a single package on gramophone record, cassette, compact disc, or via digital distribution, however the concept is found in printed music dating into the early nineteenth century in works by composers such as Schumann and Mendelssohn. The word derives from the Latin word for list.

Today, with the vinyl record no longer being used as the primary form of distribution, the term "album" can still be applied to any sound recording collection, such as those on compact disc, MiniDisc, Compact audio cassette, and digital or MP3 albums.Cover art is also considered an integral part of the album. Many albums also come with liner notes and inserts giving background information or analysis of the recording, reprinted lyrics, images of the performers, or additional artwork and text. These are now often found in the form of CD booklets.

Vinyl LP records have two sides, each comprising one half of the album. If a pop or rock album contained tracks released separately as commercial singles, these were often traditionally placed in particular positions on the album. A common configuration was to have the album led off by the second and third singles, followed by a ballad. The first single would lead off side 2. In the past many singles (such as the Beatles' "Hey Jude" and Bob Dylan's "Positively 4th Street") did not appear on albums, but others (such as the Beatles' "Come Together" and Dylan's "Like a Rolling Stone") were part of an album released concurrently. Today, many commercial albums of music tracks feature one or more singles, which are released separately to radio, TV or the Internet as a way of promoting the album. Albums have also been issued that are compilations of older tracks not originally released together, such as singles not originally found on albums, b-sides of singles, or unfinished "demo" recordings.
