Miranda Hill (Wisbech 1836–1910) was an English social reformer. She worked closely, from 1891, with her more famous sister Octavia Hill on major housing reform projects in England. She was the daughter of James Hill, corn merchant and banker, and Caroline Southwood Smith, the daughter of Dr Thomas Southwood Smith, the pioneer of sanitary reform. The sisters were brought up in reduced financial circumstances, and were never formally schooled.
