Stanley Lloyd Greigg (May 7, 1931 – June 13, 2002) was an American politician who served one term as a member of the U.S. House of Representatives from northwestern Iowa.

Greigg was born in Ireton, Iowa, and spent his earliest years there and in nearby Hawarden, where his parents were involved in the restaurant business.

at Morningside College in Sioux City in 1954, then spent two years at Syracuse University in graduate work in the Maxwell School of Citizenship and Public Affairs.

He returned to Sioux City to serve as the Dean of Men of Morningside College, where he also taught speech and history courses.

While holding that position, Greigg's name again surfaced in Iowa in the summer of 1968, when the leading candidate in the Democratic primary race for his former seat withdrew without explanation on the eve of the district convention.

[2] Griegg was hesitant to jump into the race, however, and his party's support went to his former legislative aide, Jerry O'Sullivan, who won the nomination but lost to Mayne in a landslide.

[3] Awakened early that morning by a call from a D.C. policeman and informed that his offices had been burglarized, Greigg asked, "did you catch the kids?"

At the time of his death, he was serving as vice president of the metropolitan Washington synod of the Evangelical Lutheran Church in America.
