João Afonso Telo de Menezes (died 1381)[1] was a Portuguese nobleman, 1st Count of Ourém and 4th Count of Barcelos.

[2] João Afonso Telo was the second son of Afonso Martins Telo "Raposo"[3] and Berengária Lourenço de Valadares,[4] daughter of Lourenço Soares de Valadares — advisor to kings Afonso III and Denis of Portugal — and his second wife Sancha Nunes de Chacim.

[6] João Afonso Telo was a trusted advisor of King Pedro I and his son King Fernando I of Portugal, married to his niece, Leonor Teles.

[7] He was also the alferes-mor of King Pedro I who on 10 October 1357 made him Count of Barcelos[4] and appears with the title of Count of Ourém in December 1371 after King Fernando I had given him the town of Ourém in January of the previous year but without the title of count at that time.

[8] He died during the Christmas holidays in 1381 and was buried at the Graça Church in Santarém,[1] which he and his wife, who was still alive in 1404 and was subsequently buried next to her husband, had founded.
