James Black Ronald (27 August 1861 – 27 July 1941) was an Australian politician.

Ronald's seat was abolished in 1906, and he attempted to gain Labor endorsement to contest the neighbouring Melbourne Ports.

When this endorsement was given to James Mathews instead, Ronald contested the seat as an independent Labor candidate, but was unsuccessful.

He rejoined the ALP after the election, but was one of many Labor members to leave in 1916 over the issue of conscription, eventually ending up in the Nationalist Party.
