There are over 41,638 known variable stars (2008), with more being discovered regularly, so a complete list of every single variable is impossible at this place (cf. GCVS). The following is a list of variable stars that are well-known, bright, significant, or otherwise interesting.

Famous quotes containing the words list of, list, variable and/or stars:
“Feminism is an entire world view or gestalt, not just a laundry list of women’s issues.”
—Charlotte Bunch (b. 1944)
“Shea—they call him Scholar Jack—
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
Carpenters, coal-passers—all.”
—Joseph I. C. Clarke (1846–1925)
“Walked forth to ease my pain
Along the shore of silver streaming Thames,
Whose rutty bank, the which his river hems,
Was painted all with variable flowers,”
—Edmund Spenser (1552?–1599)
“Think not, Percy,
To share with me in glory any more.
Two stars keep not their motion in one sphere.”
—William Shakespeare (1564–1616)
