Swift Vets and POWs for Truth, formerly known as the Swift Boat Veterans for Truth (SBVT), was an American political organization (527 organization) of United States Swift boat veterans; former prisoners of war of the Vietnam War, formed during the 2004 presidential election campaign. It was done for the purpose of opposing John Kerry's candidacy for the presidency; the campaign inspired the widely used political pejorative "swiftboating", to describe an unfair or untrue political attack. The group disbanded and ceased operations on May 31, 2008.

SBVT asserted that Kerry was "unfit to serve" as president, based upon his alleged "willful distortion of the conduct" of American servicemen during that war, and his alleged "withholding and/or distortion of material facts" as to his own conduct during that war. SBVT stated that "Kerry's phony war crimes charges, his exaggerated claims about his own service in Vietnam, and his deliberate misrepresentation of the nature and effectiveness of Swift boat operations compel us to step forward." The group challenged the legitimacy of each of the combat medals awarded to Kerry by the U.S. Navy and the disposition of his discharge. Further, SBVT said that Kerry's later criticism of the war was a "betrayal of trust" with other soldiers, and that by his activism he had caused direct "harm" to soldiers still at war.

These claims caused tremendous controversy during the election, particularly because the organization's members had not been in a place to assess Kerry, while the Vietnam veterans who had served under him supported Kerry's version of events.^{[excessive citations]}

Registered under Section 527 of the Internal Revenue Code, SBVT publicized its criticisms of Kerry during the election campaign in a book, in television advertisements that the group ran in swing states and in the media coverage some members received. The group was the subject of several complaints to the Federal Election Commission (FEC). After the election, the group was credited by media and praised by conservatives as contributing to Kerry's defeat. The group's tactics are considered an example of a successful political smear campaign^{[excessive citations]} for its widely publicized and later discredited claims.

SBVT was formed in 2004. Membership was initially limited to veterans of the Vietnam War who at some point served in a Swift boat unit, as did Kerry.

Of the 3,500 Swift boat sailors who served in Vietnam, the names of some 250 appeared on the group's statement against Kerry; most did not serve at the same time or in the same place as Kerry. Founding members of SBVT include Rear Admiral Roy Hoffmann (retired), a former commander of Swift boat forces; Colonel Bud Day, who earned the Medal of Honor; Houston attorney John O'Neill, an officer who became commander of Swift Boat PCF 94 several months after Kerry's departure in 1969 and who appeared opposite Kerry in a televised 1971 debate between them on The Dick Cavett Show; and 13 other named veterans. Several of those who joined SBVT during the 2004 campaign were officers who had previously praised Kerry's conduct during the Vietnam War. These included Division Commander Grant Hibbard, who wrote positive evaluations of Kerry, and Commander George Elliott, who submitted Kerry for a Silver Star. SBVT asserted that it included, in total, 16 officers who served with Kerry in Coastal Division 11 as members. Despite SBVT's statements that Kerry's "entire chain of command" belonged to the group, Joseph Streuli, former commander of Coastal Division 13, Charles Horne, former commander of Coastal Squadron 1, and Art Price, former commander CTF 116, who are described in "Unfit for Command" as part of Kerry's chain of command, were not affiliated with the group.

The group's initial letter against Kerry stated "It is our collective judgment that, upon your return from Vietnam, you grossly and knowingly distorted the conduct of the American soldiers, marines, sailors and airmen of that war (including a betrayal of many of us, without regard for the danger your actions caused us). Further, we believe that you have withheld and/or distorted material facts as to your own conduct in this war." However, Kerry had posted over 100 pages of his military records at his website nearly two weeks before the issuance of the SBVT letter, and had also made his military medical records available for inspection by reporters (and provided a summary from his doctor).

Not all SBVT members said that they were signing the letter for the same reason. For example, from an interview published the day before the letter was made public: "'[Kerry] earned his medals, he did what he was supposed to do in Vietnam,' said retired Coast Guard Captain Adrian Lonsdale, who was in the chain of command above Kerry and oversaw various operations dealing with Navy swift boats of the type Kerry commanded. 'But I was very disappointed in his statements after he got out of the Navy.'"
