In April 2018, Poirier and his wife founded the Good Fight Foundation. Poirier proceeded to auction his UFC Fight Night 120 and UFC on Fox 29 fight kits as well. The money raised went to the family of a deceased Lafayette police officer and the Acadiana Outreach Center, respectively. Poirier also auctioned his UFC on FOX fight kit and used the money raised to buy 500 backpacks for school children in his hometown of Lafayette.
