This is a list of members of the South Australian Legislative Council from 1888 to 1891.
This was the second Legislative Council to be affected by the amendments to the Constitution, which provided for the Colony to be divided into four districts: (1) Central; (2) Southern; (3) North-Eastern and (4) Northern, with six members in each division; one third of each to be replaced in rotation every three years. (Previously, the whole colony acted as one electoral district "The Province" with one third replaced at General Elections every four years.)
