Protect the Harvest is an American 501(c)(4) non-profit advocacy organization founded by Forrest Lucas which opposes "the radical animal rights movement" and particularly the Humane Society of the United States (HSUS), which it calls "a wealthy and successful attack group".

[9][8] Lucas contributed almost $200,000 to oppose Question 3, a Massachusetts ballot initiative banning the sale of products from animals raised in "extreme" confinement, which passed with strong support in 2016; Protect the Harvest also underwrote a failed legal challenge to the measure.

In 2012, according to FEC records, Lucas Oil contributed $200,000 to Protect the Harvest to fund advertisements against Christie Vilsack, who challenged and lost to incumbent Iowa congressman Steve King.

[24] In 2017, Protect the Harvest and ESX entertainment produced Pray for Rain, directed by Alex Ranarivelo, which follows a young reporter (Annabelle Stephenson) as she investigates the murder of her farming father amid the 2011–17 California drought.

[25] The film advances a form of the California drought manipulation conspiracy theory, incorrectly blaming environmentalists and bureaucrats for creating a "man-made" water shortage.

[26] The film received negative reviews,[27] with Roger Moore of Movie Nation calling it a "ludicrous Lucas Oil-man financed propaganda picture",[28] and Brian Orndorf of Blu-ray.com writing, "As much as I enjoy the image of Jane Seymour blasting away with a shotgun that’s probably bigger than she is, the melodrama of the effort only manages to cripple the production.
