Disney's One Saturday Morning was a three-hour block of animated cartoons shown on the ABC network in the U.S. and on the CTV network in Canada on Saturday mornings from around 1999 to 2001. It was later replaced by ABC Kids.

It was created as a successor to the Disney Afternoon, and originally featured some of the shows that had been on it. It also inspired Disney's One Too which aired on UPN every weekday in the afternoon.

One Saturday Morning featured the following series (in order of appearance):

• Doug ("Brand Spanking New Doug")
• Recess
• Pepper Ann
• Science Court

Then later:

• Mickey's Mouseworks
• Sabrina, The Animated Series
• Disney's House of Mouse
• Fillmore!

One Saturday Morning also featured a wide variety of "wrapper" content that filled in the gaps between shows. These included:

• Mrs. Munger's class- a brief show about a "class" consisting of a talking yearbook page.
• Manny the Uncanny- live action skit in which the eccentric Manny visits some real world location
• Great Minds Think For Themselves- short animated segment featuring the genie from Aladdin (voiced by Robin Williams) in which he profiles a famous American.
