Gigadō Ashiyuki (戯画堂 芦幸) was a designer of ukiyo-e style Japanese woodblock prints in Osaka, who was active from about 1813 to 1833. He was a pupil of Asayama Ashikuni, and was also a haiku poet. Ashiyuki is best known for his ōban sized (about 14 by 10 inches or 36 by 25 centimeters), prints of kabuki actors, although he also illustrated books, and designed surimono.
Gigadō Ashiyuki used the name "Nagakuni" (長国) from about 1814 to 1821. There is another Osaka printmaker who in known as either Shūei Nagakuni or as Naniwa Nagakuni. This latter artist was a student of Nagahide and was active from about 1814 to the 1820s.
