Hirini Rawiri Taiwhanga (c. 1832 – 27 November 1890), known as Sydney Taiwhanga, was a 19th-century Māori member of the House of Representatives.
Taiwhanga identified with the Ngāpuhi iwi. He was born in Kaikohe, Northland, New Zealand in about 1832; his father was Rawiri Taiwhanga.
He unsuccessfully contested the Western Maori electorate in the 1884 election. Of eight candidates, he came last with 5.5% of the vote. In the Western Maori 1886 by-election, he came fourth out of five candidates.
He represented the Northern Maori electorate from 1887 to 1890. He was re-elected in 1890 for Northern Maori, but died on election day, aged about 55. He had also stood in Eastern Maori, and came second.
A by-election was held in the Northern Maori electorate on 7 February 1891 to replace him.
