Donald Pierce is a supervillain appearing in American comic books published by Marvel Comics. The character is depicted as a cyborg and is commonly an enemy of the X-Men.

Donald Pierce appears in the 2017 film Logan, portrayed by Boyd Holbrook.

Donald Pierce first appeared in The Uncanny X-Men #132 (April 1980), and was created by Chris Claremont and John Byrne. Byrne modeled Pierce's name and appearance after Donald Sutherland. The character's last name comes from Benjamin Franklin "Hawkeye" Pierce, Sutherland's character in the 1970 film M*A*S*H.

Donald Pierce was born in Philadelphia, Pennsylvania. He first appears as a high-ranking member of the Inner Circle of the Hellfire Club, where he holds the position of White Bishop. However, Pierce is in fact a genocidal mutant hater, and has only joined the Hellfire Club to kill the Inner Circle's other members, all of whom are mutants. In addition to hating mutants, Pierce is also bigoted towards certain nationalities and harbors a sense of self-loathing due to his cyborg status, referring to himself as "only half a man". He is the CEO and principal shareholder of Pierce-Consolidated Mining, and operates out of a mining and laboratory complex in Cameron, Kentucky. Pierce and his mercenaries kidnap Professor X and Tessa in a plot against the Hellfire Club and X-Men, but he is defeated by the Professor despite a device shielding against telepathic attacks. Pierce is handed over to Tessa of the Hellfire Club, expelled from the Inner Circle, and taken to a secret holding facility at Shaw Industries.

Many months later, Pierce is violently liberated from the holding facility. Though his rescuers are never explicitly identified, he resurfaces alongside three members of the Reavers, a band of cyborg criminals which Pierce claims to have built and assembled, and which had been all but wiped out by the X-Men. The four of them ally with Lady Deathstrike and three Hellfire Club mercenaries (Cole, Macon, and Reese) who were cybernetically enhanced by Pierce. Under Pierce's leadership, the new Reavers are dedicated to exterminating mutants, with highest priority given to the X-Men and Sebastian Shaw (CEO of Shaw Industries).

The Upstarts' members Trevor Fitzroy sends reprogrammed Sentinels to destroy the Reavers, as they are a threat to mutants and Pierce is worth a lot of "points" in the deadly game the Upstarts play. Pierce is apparently killed by the Sentinels. Pierce later resurfaces, starts an anti-mutant hate group, and enlists several members; revealing a plot to take militant terrorist actions against mutants and thwarted by the X-Men, he is beaten by Wolverine in hand-to-hand combat.

Pierce would remain with the Hellfire Club for some time, eventually showing a more adversarial relationship with Shaw as the current Black King. He heads out to an outpost in Switzerland, believed to be Apocalypse's stronghold, to obtain Apocalypse's power and secure his position within the Hellfire Club's inner circle. Pierce releases a techno-organic entity created by Apocalypse, who gravely injures him. Pierce survives, but his injuries cost him much of his remaining flesh, revealing his head to be his only remaining fully organic component.

Pierce next tries to take over Sebastian Shaw's new Hellfire Club, launching an attack and slashing Shaw's chest. Though Shaw is left critically injured and later needed to be hospitalized, Shaw is able to punch off Pierce's head. Pierce later is forcibly recruited into the Purifiers' ranks and infected with the Technarch transmode virus. Being under the control of the mutant-hunting robot Bastion, he shows his mutant target: the newly formed Young X-Men.
