The new polyazo reactive dyestuffs of the formula ##STR1## in which the substituents have the meaning given in the description are highly suitable for the dyeing or printing of hydroxyl- or amido-containing materials. The dyeings and prints obtained are distinguished by high fibre-dyestuff bonding stability and by particularly good stability to oxidizing agents.
