Sir Henry Williams Baker, 3rd Baronet (27 May 1821 – 12 February 1877), was an English Anglican priest and hymnwriter.
His grandfather was Sir Robert Baker of Dunstable House, Surrey, and of Nicholashayne, Culmstock, Devon, on whom a baronetcy was conferred in 1796.
Sir Henry Baker's name is chiefly known as the promoter and editor of 'Hymns Ancient and Modern,' first published in 1861.
The hymnal was compiled to meet the wants of churchmen of all schools, but strong objections were raised in many quarters to Sir Henry Baker's own hymn addressed to the Virgin Mary, 'Shall we not love thee.
Sir Henry held the doctrine of clerical celibacy, and at his death the baronetcy devolved on a kinsman.
