List of variable stars
{{Short description|none}}
{{As of|2017|}}, there are over 52,011 known variable stars,{{cite journal |last1=Samus' |first1=N. N. |last2=Kazarovets |first2=E. V. |last3=Durlevich |first3=O. V. |last4=Kireeva |first4=N.

GCVS). The following is a list of variable stars that are well-known, bright, significant, or otherwise interesting.
