The Walker, later Walker-Okeover Baronetcy, of Gateacre Grange in the County of Lancaster and Osmaston Manor in the County of Derby, is a title in the Baronetage of the United Kingdom. It was created on 12 February 1886 for Andrew Walker, a brewer, Lord Mayor of Liverpool, High Sheriff of Lancashire and benefactor to the city of Liverpool.

The second Baronet married Ethel Blanche, sister and co-heir of Haughton Ealdred Okeover, through which marriage Okeover Hall, Staffordshire, came into the family. The third Baronet assumed by Royal licence the additional surname of Okeover in 1956. He served as Lord-Lieutenant of Derbyshire from 1951 to 1977.

Osmaston Manor, Derbyshire, was acquired by the first Baronet in 1884. The house was demolished in 1964. The family also owns the House of Glenmuick, Ballater, Aberdeenshire.^{[citation needed]}
