Daniel Green (born May 29, 1955) is a Canadian politician, environmentalist and scientific communicator.

[5] Since the early 2000s, Green has acted as the SVP's co-chair and has been vocal against the effect of pollution on public health.

Examples of his activism are the asbestos controversy,[6] the trichlorethylene contaminated water case in Shannon,[7] the Lac-Mégantic rail disaster[8] and Montreal REM train project.

[11] As part of the Liberal government's plan to reform Canada's electoral system following the 2015 election, Green pushed for the introduction of a proportional voting system, which, in his opinion, would make the electoral process more democratic and more representative.

[12] Green ran in a federal by-election in the riding of Saint-Laurent in March 2017, which happened due to former Liberal leader Stéphane Dion's resignation from the House of Commons.
