Charles Edward Button was a solicitor, Supreme Court judge, Mayor of Hokitika and later Birkenhead, and an independent conservative Member of Parliament in New Zealand. Born in Tasmania, he came to New Zealand with his wife in 1863. He first lived in Invercargill, then in Westland, and after a brief period in Christchurch, he settled in Auckland. He was an MP for two periods, and when he was first elected to Parliament, he beat his colleague, friend, political opponent, and later Premier Richard Seddon; this was the only election defeat ever suffered by Seddon.
