Áron Tamási (born: János Tamás; 20 September 1897 – 26 May 1966) was a Hungarian writer. He became well known in his native region of Transylvania and in Hungary for his stories written in his original Székely style.
Born to a Székely family in Farkaslaka in Udvarhely County (present-day Lupeni, Harghita County), he graduated in Law and Commerce at the Babeş-Bolyai University, Tamási emigrated to the United States in 1923, soon after Transylvania became part of Romania. He wrote his first Hungarian-language novels there, and these were soon published in Cluj-Napoca, to widespread acclaim. He returned home in 1926 and lived in Transylvania until 1944.
One of Tamási's most famous works from this period was a novel trilogy about the adventures of a Székely boy called Ábel, a young forest ranger living alone in the Hargita Mountains. Tamási moved to Budapest in 1944, and lived there until his death in 1966. At his request, he was buried in the Székely Land, an ethno-cultural region in eastern Transylvania, Romania.
