Lin Join-sane is a Taiwanese politician. He was the chairman of the Straits Exchange Foundation from 27 September 2012 until 20 May 2016.

The Straits Exchange Foundation is a semiofficial organization set up by the Government of the Republic of China (Taiwan) to handle technical and/or business matters with the People's Republic of China (PRC). Though technically a private organization, it is funded by the government and under the supervision of the Mainland Affairs Council of the Executive Yuan. Its role is effectively to function as the de facto embassy to the PRC, as a means of avoiding acknowledgement of the PRC's statehood status.
