Mayereen Viray was a female Petarian in the 24th century.

In 2385, Quark hired Viray to attempt to locate Morn, who Quark had not seen since the previous year. Viray visited Micsim IV in search of Morn, before finding a worthwhile lead to Morn on the cloud city of Stratos on Ardana. (DS9 novel: Sacraments of Fire)

Viray later found another lead on Morn's whereabouts on Geopolis on Janus VI. (DS9 novel: Ascendance)
