Katharine "Kate" Louisa Russell, Viscountess Amberley (née Stanley; 3 April 1842 – 28 June 1874) was a British suffragist and an early advocate of birth control in the United Kingdom.

According to their younger son, the Amberleys were concerned for his celibacy and "allowed him to live with her", though Russell wrote that he knew of "no evidence that she derived any pleasure from doing so".

[3][6] Following a suffrage meeting held in Hanover Square Rooms in 1870, the Countess Russell told her son that she appreciated the fact that his wife had not taken part in it.

Their deaths greatly affected Lord Amberley, whose decision to have their bodies cremated without religious ceremony shocked English society.

Shortly after her husband's death two years later, all three sets of remains were moved to the Russell family vault at St Michael's, Chenies.
