H. A. Milne (fl. 1879 - 1887) was a British draftsman and cartographer. Milne joined the in-house drawing office in 1879 as an assistant to William John Turner. When Turner resigned in 1881 to join W. And A. K. Johnston in Edinburgh, Milne applied for the position but was overlooked in favor of Henry Scharbau (anglicized Sharbau). Milne continued on as Sharbau's assistant until 1887 when the Royal Geographical Society let him go because of ill-health and prolonged absence.
