Thomas J. Mulcahy (10 January 1923 – 9 November 2009) was an Irish hurler who played as a goalkeeper at senior level for the Cork county team.
At club level Mulcahy was a four-time county senior championship medalist with St Finbarr's.
Ballincollig, a team who had defeated nine-in-a-row hopefuls Glen Rovers in the semi-final, provided the opposition.
In a changing of the guard, Mulcahy came on as a substitute for regular 'keeper Jim Buttimer to collect his first championship medal on the field of play.
A 3–3 apiece draw, thanks to a late goal by Seán Condon, was the result on that occasion; however, St Finbarr's made no mistake in the replay and powered to a 7–9 to 1–1 victory.
A record crowd saw "Sars" lead "the Barr's" by a single point as the game entered injury time.
They failed to clear a seventy which was flicked to the net by Jim Sargent to give St Finbarr's a 4–6 to 4–4 victory.
The year got off to a good start when Cork defeated Limerick by 4–6 to 3–6 after a replay to give Mulcahy a second Munster medal.
Under the captaincy of Christy Ring, Cork subsequently faced old rivals Kilkenny in the All-Ireland final.
With ten minutes remaining Cork's lead was reduced to just two points, however, goals by Mossy O'Riordan and Joe Kelly secured the victory.
Cork retained their provincial dominance in 1947 with Mulcahy picking up a fourth winners' medal following a three-point victory over Limerick.
A Joe Kelly goal put Cork one point ahead with time almost up, however, Terry Leahy proved to be the hero of the day.
After back-to-back championship exits at the hands of Tipperary in 1949 and 1950, Mulcahy decided to retire from inter-county hurling.
