Dragutin Milivoj Domjanić (12 September 1875 – 7 June 1933) was a Croatian poet.
Domjanić was born in Krči (now Adamovec, Croatia), a village near the town of Sveti Ivan Zelina. Having graduated law, he served as a judge in Zagreb and as a counsellor for the Ban's Bench. He was a member of Yugoslav Academy of Sciences and Arts, the president of Matica hrvatska (1921–1926), and the president of Yugoslav PEN Club. In the struggle between the "old" and the "young" in the framework of Croatian Modernism, he sided with the "young". He versified motifs such as spiritual love, intimacy of the nobility mansions, marquises and cavaliers of the past days. He feared the brutality of the present, mourned the world dying off, he was incredulous of new ideas.
Domjanić wrote in his native Kajkavian dialect. The most notable work of Domjanić is a Kajkavian poem collection Kipci i popevke, and the poems "Fala" and "Popevke sam slagal", both set to music by Vlaho Paljetak. Croatian composer Ivana Lang also set to music several Domjanić's poems. His lyrical expression, idyllic and sentimental, abounds both by the picturesqueness and musicality. He became the first writer in Croatian literature to achieve complete and artistically mature melodiousness and rhythmicity of the Croatian Kajkavian expression.
All of his poems were written in Kajkavian literary language of the period, although his vernacular was Kajkavian dialect of Adamovec. He also wrote a number of literary accounts, and a few prosaic notes, chiefly in the spirit of his lyrical interests and stylistic manner.
He is also the author of the lesser-known string puppet play Petrica Kerempuh and the Smart Ass (Kajkavian ), writing under the pseudonym Vujec Grga.
Some of his poetic work has been translated into Esperanto by Zvonko Rehoriĉ, such as Sub suno kaj ombro.
He died in Zagreb.
