Ryszard Tadeusz Koncewicz (12 April 1911 – 15 March 2001) was a Polish footballer and manager.

In the interbellum period, Koncewicz played without notable successes for Lechia Lwów (1927–1939).

Caught by the Wehrmacht during the Polish September Campaign, he spent the war in a German POW camp Oflag IIC Woldenberg, where he represented the unofficial team of the city of Lwów, which consisted of POWs.

As early as 1948, Koncewicz started cooperating with then-coach of the Poland national team, Wacław Kuchar, who himself was from Lwów as well.
