Henry N. Beard (born ca. 1945) is an American humorist, one of the founders of the magazine National Lampoon and the author of several best-selling books.

Beard, a great-grandson of Vice President John C. Breckinridge, was born into a well-to-do family and grew up at the Westbury Hotel on East 69th Street in Manhattan. His relationship with his parents was cool, to judge by his quip I never saw my mother up close.

He attended the Taft School, where he was a leader at the humor magazine, and he decided to become a humorous writer after reading Catch-22.

He then went to Harvard University from which he graduated in 1967 and joined its humor magazine, the Harvard Lampoon, which circulated nationally. Much of the credit for the Lampoons success during the mid 1960s is given to Beard and Douglas Kenney, who was in the class a year after Beards. In 1968, Beard and Kenney wrote the successful parody Bored of the Rings.

In 1969, Beard, Kenney and Rob Hoffman became the founding editors of the National Lampoon, which reached a monthly circulation of over 830,000 in 1974 (and the October issue of that year topped a million sales). One of Beards short stories published there, The Last Recall, was included in the 1973 Best Detective Stories of the Year. During the early 1970s, Beard was also in the Army Reserve, which he hated.

In 1975 the three founders cashed in on a buy-out agreement for National Lampoon; and Beard left the magazine. After an unhappy attempt at screenwriting, he turned to writing humorous books.
