General Sir Robert Hadden Haining, KCB, DSO, JP (28 July 1882 – 15 September 1959) was a senior British Army officer during the Second World War.

[2] Following his death, his friend George Richard Hodges Nugent (later Baron Nugent of Guildford) wrote to The Times to remark on Haining's character and post-retirement life: When he resigned from the Army, despite weighty grounds for complaint, he wasted no time in repining but immediately made himself available for public work of all kinds, from the parish to the county.

When he returned home after his last evening engagement he would embark on his large personal and official correspondence, all written in his own strong characteristic handwriting, for secretarial staff was not within his means.

His great energy, shrewd common sense and active brain will be much missed from a wide range of administrative work in the county.

Even more, his warm, lovable personality will be missed by a multitude of men and women in every walk of life who knew him as their friend.
