The 1892 Cardiff County Borough Council election was held on Tuesday 2 November 1892 to elect councillors to Cardiff County Borough Council in Cardiff, Wales. These were the fourth all-Cardiff elections since the creation of the county borough. The previous elections were in November 1891 and the next elections were in November 1893.

The Liberal Party remained the largest party after the election, but with reduced numbers.

Cardiff had become a county borough in April 1889. The council consisted of 30 councillors who were elected by the town's voters and ten aldermen who were elected by the councillors.^[1] Elections took place every November. Not all council seats were included in each contest, because the three councillors in each ward stood down for election in three-yearly rotation.

Ten councillor seats were up for public election in November 1892.

Contests took place in eight of the ten electoral wards. The candidates in the Central and South wards were re-elected unopposed.^[2]

The Western Mail described the 58% turnout as making the election "the most uneventful on record in the history of the town" with interest in Cardiff elections "fallen off marvellously".^[3] The Progressive Labour candidates took some votes away from the sitting Liberal candidates, except for the Cathays ward where the Liberals put their support behind the Labour nominee.^[2]

As a result of the election, the Liberal Party lost three seats, two of which were gained by the Conservatives and one by Labour candidates. The Liberals remained the largest party on the council, with 23 seats. the Conservatives had 14 seats and Labour members held two.^[2] A vacancy remained in the Cathays ward, due to the death of a Liberal councillor, Peter Price.^[2]
