David George Thompson (born 20 September 1949) is a Scottish former politician who was the leader of Action for Independence (AFI) from 2020 to 2021.

Prior to entering politics, he had a long career in local government, ending as Director of Protective Services for the Highland Council.

[2] Thompson received some media attention in the aftermath of the 2007 election because he pointed out to the returning officer that the number of additional members for each party had been wrongly calculated.

"[6] He told The National he believed the new movement could help create a "supermajority" in Holyrood at the expense of the Tories, Labour and the Lib Dems.

[8][9][10] On 26 March 2021, Thompson stated that AFI would be standing down all of their candidates in order to support the Alba Party in the 2021 election.
