The Kaiser roll is a typically crusty round bread roll, originally from Austria. It is made from white flour, yeast, malt, water and salt, with the top side usually divided in a symmetric pattern of five segments, separated by curved superficial cuts radiating from the centre outwards or folded in a series of overlapping lobes resembling a crown.

Kajzerki pochodzą najprawdopodobniej z Wiednia, a nazwane zostały na cześć cesarza (niem. kaiser) Franciszka Józefa.
