Ioan Volcinschi (May 5, 1846–May 27, 1910) was an ethnic Romanian physician and politician in the Duchy of Bukovina, within Austria-Hungary.
He was a public health adviser, vice president of the Bukovina medical association and professor of hygiene at the seminary institute of the Orthodox Metropolis.
In 1890, he joined the Concordia political society, and was a founding member of Gazeta Bucovinei.
He was concerned with fighting against pellagra, then a rather widespread ailment, proposing dietary changes in the villages where it was detected.
In 1883, he published the first Romanian-language textbook of midwifery; the book tended to use Romanian rather than specialized foreign vocabulary.
