Umar Marvi or Marui (Sindhi: عمر مارئي) is a folktale from Sindh, Pakistan about a village girl Marvi Maraich, who resists the overtures of a powerful King and the temptation to live in the palace as a queen, preferring to be in simple rural environment with her own village folk.
The story also appears in Shah Jo Risalo and forms part of seven popular tragic romances from Sindh, Pakistan. The other six tales are Sassui Punhun, Sohni Mehar, Lilan Chanesar, Noori Jam Tamachi, Sorath Rai Diyach and Momal Rano commonly known as the Seven Queens of Sindh, or the Seven heroines (Sindhi: ست سورميون) of Shah Abdul Latif Bhittai.
