Benjamin Harris (1836–1928) was a 19th-century Member of Parliament in New Zealand. In 1893 he appears to have been a Liberal Party supporter.
He represented South Auckland electorates; Franklin from 1879 to 1881; and then the replacement electorate of Franklin North from 1881. His 1881 election was declared void in 1882, but he won the subsequent 1882 by-election. In 1884 he was defeated. He then represented the reconstituted Franklin electorate from 1893 to 1896, when he was again defeated, by future Prime Minister William Massey.
On 3 February 1897, he was appointed to the Legislative Council. At the end of the seven-year terms, he was reappointed in 1904, 1911 and 1918. He resigned on 20 June 1923.
