Ochna integerrima is a tree species (sometimes shrub) of the family Ochnaceae. The spectacular yellow flowers of this plant make it very popular in southern Vietnam, where the plant is purchased during Tết, the traditional Vietnamese New Year. Ochna integerrima is also the provincial flower of Mukdahan province, Thailand.
In Vietnamese, the variety of O. integerrima whose flowers have five petals is called mai vàng (yellow mai), whereas mai núi (mountain mai) flowers have between five and nine petals
