Avrohom Eliyahu (Elya) Kaplan (Hebrew: אברהם אליהו קפלן; 1890–1924) was a prominent Ashkenazi Orthodox rabbi.
He was born an orphan, and named Avrohom Elya for his deceased father, who had died suddenly at the age of 33 several months before his son's birth.
At 16, he was drawn to the spirit of the Mussar movement, and went to learn in the Talmud Torah in Kelm, the yeshiva founded by Rabbi Simcha Zissel Ziv.
Avraham Elya studied in Slabodka for seven years, until the outbreak of World War I left him stranded in his mother's home in Telshe.
In his youth (at the age of seventeen), his fiery nature induced him to compose a poem portraying impending doom and angst.
