Arqba (Classical Mandaic: ࡀࡓࡒࡁࡀ), alternatively known as Mašrwan (Classical Mandaic: ࡌࡀࡔࡓࡅࡀࡍ, romanized: Mašruan), is the tenth month of the Mandaean calendar.
It is the Mandaic name for the constellation Scorpio. It currently corresponds to April / May in the Gregorian calendar due to a lack of a leap year in the Mandaean calendar.
