Ihram (إحرام iḥrām, from the triconsonantal root Ḥ-R-M) is, in Islam, a sacred state which a Muslim must enter in order to perform the major pilgrimage (Hajj) or the minor pilgrimage (Umrah). A pilgrim must enter into this state before crossing the pilgrimage boundary, known as Miqat, by performing the cleansing rituals and wearing the prescribed attire.

Ihram clothing is simply an item of clothing to be worn during the pilgrimage, but there are many competing views on the proper wearing of ihram. For example, the exact number of days a pilgrim is required to wear ihram varies according to the type of pilgrimage (Hajj) the individual is performing. The simple, white Ihram clothing is intended to make everyone appear the same, as Muslims believe that in the eyes of God there is no difference between a prince and a pauper. For women there is no clear prescription. Women's clothing, therefore, varies considerably and reflects regional as well as religious attitudes. In general female Hajji (women who have completed the Hajj) clothe themselves in long robes, covering the body from head to foot and leaving the face and hands exposed.
