Sandra Keith Boynton (born April 3, 1953) is an American humorist, songwriter, director, music producer, children's author, and illustrator.

The third of the four daughters of Jeanne (née Ragsdale) and Robert W. Boynton, Sandra was born in Orange, New Jersey, and grew up in the Mount Airy section of Philadelphia.

Boynton has frequently cited Germantown Friends' arts-centered curriculum as central to her own "upbeat offbeat" sensibility as well as its thorough integration of the values of pacifism, independent inquiry, and individualism.

She had joined the Glee Club when additional singers were needed for a performance of Beethoven's Ninth Symphony at Carnegie Hall, under the direction of Leopold Stokowski.

Boynton's grade point average did not in fact entitle her to any degree honor; but shortly before the ceremony, she had told Professor Davis in mock earnest that "my parents are here, so I'd really appreciate it if you could just mumble some Latin after my name".

With the birth of her first child in 1979, Boynton postponed indefinitely a career in the theater, judging the demands of that profession not easily compatible with raising a family.

In an autobiographical talk given at Yale in 2002, "The Curious Misuse of a Yale Education", Boynton refers to her book Grunt (an illuminated book and recording of plainchant in Latin and Pig Latin) as "the culmination of a lifetime spent joyfully squandering an expensive education on producing works of no apparent significance".

According to RPG co-founder and president Mike Keiser, nearly 500 million copies of Boynton's distinctive humorous cards—featuring an assortment of unnamed cartoon animal characters, spare layout, and droll messages—sold between 1973 and 2003.

[citation needed] In May 1995, Boynton wrote and directed a benefit reading, On Stage—featuring Jill Clayburgh, Joe Pacheco, and Jane Curtin—for Sharon Stage in Connecticut.

In 1996, Boynton began writing and producing songs—which she has described as "renegade children's music" — with composer Michael Ford; these songs have been released as albums (Rhinoceros Tap 1996, Philadelphia Chickens 2002, Dog Train 2005, BLUE MOO: 17 Jukebox Hits from Way Back Never 2007, FROG TROUBLE Fall 2013 and Hog Wild in 2017) and also published as book and audio disc sets.

The tracks were recorded, under Boynton's direction and Ford's musical direction, by an eclectic roster of actors and musicians, including Blues Traveler, Meryl Streep, Alison Krauss, Steve Lawrence, and Eydie Gorme, John Ondrasik of Five for Fighting, Kevin Kline, Laura Linney, "Weird Al" Yankovic duetting with Kate Winslet, Patti LuPone, The Bacon Brothers with Mickey Hart, Eric Stoltz, the Spin Doctors, Mark Lanegan, Hootie & the Blowfish, Natasha Richardson, Billy J. Kramer, Scott Bakula, Eric Bazilian and Rob Hyman, The Phenomenauts, Brian Wilson, Neil Sedaka, B.B.

King, Sha Na Na, Steve Lawrence, Bobby Vee, Gerry & The Pacemakers, Davy Jones of The Monkees, Dwight Yoakam, Fountains of Wayne, Kacey Musgraves, Ryan Adams, Ben Folds, Brad Paisley, Josh Turner, Darius Rucker, and Linda Eder.

Boynton is currently working on a Christmas album entitled Cows and Holly with producer Mike Ford, due for release in September 2024.

Boynton was married to writer and Olympic Bronze medalist (and fellow Yale graduate) Jamie McEwan from 1978 until his death from cancer in 2014.
