Anthony Traill (November 1, 1838 - October 15, 1914) was a provost of Trinity College Dublin.

Born at Ballylough, in county Antrim, Anthony Traill matriculated at Trinity College Dublin. He became a fellow in 1865, and while at college he accumulated degrees in engineering, law and medicine.

Although he was most famous for the position he would acquire later in life, Traill was actually involved in politics during the 1870s and 1880s. He was an Ulster Unionist, but he sided with the landlords during the debate over land tenure reform. In 1884 he was appointed high sheriff of Antrim. He also became the chairman of the world's first electric tramway, Portrush. The Portrush electric tramway ran from Portrush to Bushmills from its inception in 1883 (with Traill as chairman) until 1947.

In 1904, Traill was appointed provost of Trinity College Dublin. During his hold of the office, he carried out many internal reforms. Traill refused to change the college's constitutional position at any time in his provosthood despite pressure. He remained the provost until he died, at the Provost's House, in 1914.
