A song whose purpose is to educate.
It need not be strictly educational (for instance, in the context of a work of fiction, it may also serve to further the plot).
Educational songs are expected to crop up a lot in science shows or edutainment shows. A special case is when the educational song happens to be a Protest Song: these tend to be crash courses in political theory, economics, philosophy, or other subjects many find heavy going.
- Momotaro's Divine Sea Warriors has a long musical number in which the animals sing "The Song of AIUEO", a Real Life traditional song children sing when learning the Japanese alphabet.
- Pleasant Goat and Big Big Wolf: While earlier episodes of the educational Spinoff Babies series Pleasant Goat Fun Class weren't guaranteed to have a song at the end, the producers eventually decided to stick with having a musical piece as the last segment of each episode to reinforce the lesson being given (e.g. songs about the atmosphere and the water cycle in the season The Earth Carnival and songs about countries like Australia, Japan, and Mexico in the season Travel Around the World).
- The "Galaxy Song" in Monty Python's The Meaning of Life is surprisingly educational for a Big-Lipped Alligator Moment in a Monty Python film.
- The various songs at the end of every episode of Bill Nye the Science Guy.
- In Horrible Histories (the live-action show), there is plenty of these.
- Naturally songs from children's education shows.
- Songs on Sesame Street, The Electric Company (1971), The Electric Company (2009), and Square One TV, obviously.
- The Sesame Street Greatest Hits Album Sesame Street Platinum All Time Favorites, which was added to the National Recording Registry in 2014, has several of these:
- "Bein' Green", "Fuzzy and Blue (and Orange)" and "We Are All Earthlings" are both about accepting yourself and that everybody is different, but we are all people on the same Earth.
- " 'C' Is For Cookie" is about the fact that the letter "c" is used for the word cookie.
- "One Fine Face", sang by Ernie and Elmo, about the different parts of the face.
- "Put Down The Duckie" is about focusing on what you want to do and not being distracted by other things.
- Rock N Learn videos are basically videos set to these.
- The various children's songs about the alphabet, colours and numbers.
- Hank Green has these with "Protons and Neutrons", "Strange Charm", "Phineas Gage", "The Universe is Weird" and then some.
- The most popular song of 1959 was "The Battle of New Orleans" by Johnny Horton, which was a song that thought about the same battle in 1815 (with some embellishment for comedic effect). The song was actually most popular with teens and college students, which is impressive because it was a folk-country song about a topic they'd learned about in history years ago and it was during the height of the golden age of rock and roll.
- Older Than Radio is "Low Bridge" (Fifteen Years/Miles On The Erie Canal) from 1906, an educational song about the Erie Canal. It was adopted almost a century later by Animaniacs as "Panama Canal" and the latter is much better known now due to the "Weird Al" Effect (and the song having become obscure over the decades), though there are some who might know the original version from VeggieTales, where Pa Grape covered it.
- Tom Glazer and Dottie Evans' Space Songs album had a variety of children's songs about science, with a focus on astronomy. You can read the CD booklet here.

- "Meet James Ensor", is a song that provides biographical information about "Belgium's famous painter".
- "James K. Polk" is an autobiographical song about the US president famously nicknamed the "Napoleon of the Stump".
- "Mammal" features lyrics that drop all sorts of trivia about mammals, including an obscure reference to the extinct infraclass Allotheria.
- "Why Does the Sun Shine?" is their famous cover of a 1959 educational song about the Earth's sun. For Here Comes Science, they released an updated, more scientifically-accurate song called "Why Does the Sun Really Shine?"
- "The Bloodmobile" is a song about the circulatory system created for an exhibit at the Franklin Institute Museum in Philadelphia, PA.
- Tom Lehrer also created some of these including "The Elements", "New Math", and "Silent E"; several of the word-themed songs furnished the material for animated segments on The Electric Company (1971).
- Louis Armstrong's "Now You Has Jazz" is a song that describes how Jazz is constructed.
- Peter and the Wolf by Sergei Prokofiev, which is a classical composition accompanied by a storyteller telling a fairy tale. The educational part is in the introduction, where the narrator explains which instrument portrays which character. Generations of children have learned to identify the different instruments in the orchestra thanks to this musical tale.
- Renald Francoeur produces rare catchy pop/hip-hop examples of this trope that are released by Marbles the Brain Store. Notable mentions include "Tour the States" and "Tour the World".
- The Young Person's Guide To The Orchestra by Benjamin Britten is another classical composition where a narrator explains how a classical orchestra is constructed by introducing all the instruments as characters.
- "Word Crimes" by "Weird Al" Yankovic manages to turn a "Blurred Lines" parody into a lesson on proper grammar.
- Some MiniMoni songs teach educational concepts due to the group being aimed at a younger demographic of kids than Morning Musume. For instance, "Rock n' Roll Kenchoushozaichi" teaches the names of all 48 prefectures of Japan, and "MiniMoni Kazoeuta" teaches how to count to twenty, with the "Ofuro version" having an entire verse where they count to twenty in English.
- Parodied by Avenue Q and the infamous "The Internet Is For Porn".

To understand all the references you often have to consult an encyclopaedia or look up more about them.
- StoryBots is a collection of songs about various educational subjects, such as the alphabet and body parts, animated to feature the titular robots.
- Animaniacs had lots of these, including songs for all the U.S. presidents up to Bill Clinton, the 50 states and their capitals, and of course, the famous Nations of the World song.

- Some of Rockapella's full-length songs on Where in the World Is Carmen Sandiego? used when the show ran short. There was one about the five largest islands in the world.
