Martabak or murtabak, also mutabbaq, (Arabic: مطبق‎) is a stuffed pancake or pan-fried bread which is commonly found in Saudi Arabia (especially the Hejaz region), Yemen, Indonesia, Malaysia, Thailand, Singapore, and Brunei. Depending on the location, the name and ingredients can significantly vary. The name mutabbaq (or sometimes mutabbag) in Arabic means "folded".

In Malaysia, where it is called "Murtabak", it is sold by Mamak salesmen, and usually includes minced mutton, along with garlic, egg and onion, and is eaten with curry sauce. Murtabak also usually includes mutton in Yemen. In Indonesia, particularly Jakarta, it is called "martabak", and has two versions: a sweet one, and a savory one. Vegetarian murtabaks exist, too, and can be found around Singapore's "Little India" neighborhood, among other places.

Murtabak originated in Yemen and hijaz region of Saudi Arabia the word mutabbaq in Arabic means folded,through traders it has spread to India and southeast of Asia. The dish referred to as Murtabak is a multi layered pancake that originated in the state of Kerela where the people referred to disparagingly as "mamak's" (or uncle) hail from. The word mutabar is the correct name for the particular dish referred to incorrectly as murtabaq. Mutabar is an amalgam of two words, muta (being the Kerelite word for egg. a significant component of the dish) and "bar" an abbreviated form of the word barota, or "bratha roti" (the bread the egg is added on to make the dish). The bread base or pancake on which it is then spread over is referred to in Hindi as pratha roti or pratha. (Note the difference in pronunciations, pratha and brata).
