* ActorAllusion: The "[[https://www.youtube.com/watch?v=0LXXSY4mhBk My Fluffy Puppy]]" ImagineSpot is a clear parody of Franchise/MyLittlePony, and even has a SuspiciouslySimilarSong version of the classic commercial theme song. Martha's voice actress Creator/TabithaStGermain has voiced several ponies over the years, including Minty from the G3 series and Rarity from ''WesternAnimation/MyLittlePonyFriendshipIsMagic''
** Doubly hilarious when you realize that ''Martha Speaks'' was animated by Vancouver-based Studio B. [[WesternAnimation/MyLittlePonyFriendshipIsMagic Guess which show that crew would be working on next.]]
** Speaking of the aforementioned series, this show once again has Nicole Oliver voicing an elementary school teacher who has students played by Madeleine Peters and Michelle Creber.
* AdoredByTheNetwork: PBS loved promoting Martha Speaks when it was a popular series from 2008 to 2014, it would have promos after a lot of ''WesternAnimation/{{Arthur}}'' episodes most stations and its national feed gave it two slots in the morning and afternoon before the PBS Kids Preschool Block and PBS Kids Go!
* ChildrenVoicingChildren: Most of the children were voiced by kids.
* TheDanza: In "Too Many Marthas", Martha meets a young woman named Jennifer (voiced by Creator/JenniferGarner).
* DawsonCasting: 11-year-old Carolina was voiced by Vanesa Tomasino, who was in her late twenties/early thirties during the show's run.
* FakeNationality: Mariela (Helen's mom) and her niece Carolina are of Mexican origin, but are voiced by Canadian Tabitha St. Germain and Salvadoran Vanesa Tomasino, respectively.
* ProductionPosse: Ken Scarborough, the head writer, brought over many people who worked with him on ''WesternAnimation/{{Arthur}}'' and ''WesternAnimation/CuriousGeorge'', including Peter K. Hirsch, Joe Fallon, Kathy Waugh, Raye Lankford, and many more.
* RecursiveAdaptation: A number of stories from the television show have now been released as books.
* ReferencedBy: The series' lore was the subject of one of WebVideo/AthenaP's Lore videos. Athena mentions that she adores Martha.
* ScrewedByTheLawyers: The show never continued past season 6 due to a lawsuit. Susan Meddaugh, whose books inspired the TV show, [[https://www.bostonglobe.com/business/2013/06/05/author-martha-speaks-children-books-sues-wgbh-for-slice-donations/gIBFgm1Zkk0m5Fl3GVUzhK/story.html sued WGBH]] and alleged she was cheated out of royalties. As an added rotten cherry on top, the show was funded by Chick-Fil-A, notorious for its homophobia, which Meddaugh is against. The lawsuit also led to the series' final two seasons not being distributed outside of the United States and Canada.
* ScrewedByTheNetwork: As of October 2022, reruns of the show stopped airing on the 24/7 channel due to PBS' broadcasting rights to the series expiring.
* WhatCouldHaveBeen: According to Creator/TabithaStGermain, the role of Martha was originally offered to Creator/EllenDeGeneres.
