* [[Julie Andrews]] as [[Mary Poppins (character)|Mary Poppins]], a magical and loving woman who descends from the clouds in response to the Banks children's advertisement for a nanny. She is firm in her use of authority but gentle and kind as well, a major departure from the original books, in which the character was more stern and pompous.{{sfn|Grilli|2013|p=back cover}}
* [[Dick Van Dyke]] as Bert, a [[cockney]] [[Jack of all trades, master of none|jack-of-all-trades]] and Mary Poppins' closest friend, who is completely accustomed to her magic. Their playful interactions imply that they have known each other for a long time and that this kind of story has repeated itself many times. Bert has at least four jobs throughout the film: a [[one-man band]], a [[sidewalk chalk]] artist, a [[chimney sweep]], and a kite seller.
** Van Dyke also portrays Mr. Dawes Sr., the old director of the bank where Mr. Banks works. During the film's end titles, "Navckid Keyd", an anagram of Dick Van Dyke, is first credited as playing the role before the letters unscramble to reveal Van Dyke's name.
* [[David Tomlinson]] as George Banks, Mary Poppins' employer and strict, driven, and disciplined father of Jane and Michael. He works at the Dawes Tomes Mousley Grubbs Fidelity Fiduciary Bank in London.
* [[Glynis Johns]] as Winifred Banks, the easily distracted wife of George Banks and the mother of Jane and Michael. She is depicted as a member of [[Emmeline Pankhurst]]'s "[[Women's suffrage in the United Kingdom|Votes for Women]]" suffrage movement. Mrs. Banks was originally named Cynthia, but this was changed to the more English-sounding Winifred per Travers.<ref name= historyvshollywood>{{cite web|last=Lang|first=Kevin|url= https://www.historyvshollywood.com/reelfaces/saving-mr-banks.php|title= Saving Mr. Banks True Story|work= [[History vs. Hollywood]]|date=December 19, 2013|access-date= September 9, 2020|archive-date= September 19, 2020|archive-url= https://web.archive.org/web/20200919083524/https://www.historyvshollywood.com/reelfaces/saving-mr-banks.php|url-status= live}}</ref>
