Stephen MacKenna (15 January 1872 – 8 March 1934) was a journalist, linguist and writer of Irish descent. He is perhaps most well known for his important English translation of the Greek-speaking philosopher Plotinus (c. 204/5 – 270), introducing Neoplatonic philosophy to a new generation of readers.

MacKenna's prose style was widely admired and he influenced many of his contemporaries, including W. B. Yeats, W. B. Stanford and J. M. Synge.
