David Creighton (April 1, 1843 – November 7, 1917) was an Ontario businessman and political figure. He represented Grey North in the Legislative Assembly of Ontario from 1875 to 1890 as a Conservative member.

He was born in Glasgow, Scotland in 1843; his parents were of Irish descent. Creighton came to Canada West with his family in 1855. He became editor and publisher of the Owen Sound Times in 1864, retiring in 1896. In 1873, he married Jane Elizabeth Kramer. He was first elected to the assembly in an 1875 by-election held after the election of Thomas Scott was declared invalid.

The community of Creighton Mine, now a ghost town in Greater Sudbury, was named after him. He died in 1917.^[1][2]
