(21 August 1848 – 10 June 1911) was a Canadian Catholic priest, professor, journalist, and academic administrator at the University of St. Michael's College in Toronto, Canada.

Charles Vincent, CSB, Teefy worked with Vice-Chancellor Sir William Mulock to make St. Michael's the first to federate with the University of Toronto.

Henry Carr, CSB, would write that Teefy was instrumental in the founding and formulation of the modern University of Toronto and would set a standard for the organization of Canadian higher education, which would follow the model that he and Murlock created.

[7] It also created an important precedent, Carr suggests, that demonstrated that Catholic and Protestant educational institutions, which has historically been separated, could enjoy a productive coexistence within the same organization.

[9] Following his time at St. Michael's College, in 1903 Teefy was named the pastor of Holy Rosary Parish in Toronto.

He remained active journalist through the remainder of his life, serving as the chief editor of the Catholic Record beginning in 1904.

Father Teefy's influence for good was infeed wide and far-reaching, and this diocese met with a great blow in his death.
