William Frank Ryan (May 21, 1949 – November 19, 2021) was an American voice actor and producer–writer–composer, well-known for singing about the American West. In the late seventies he teamed up with Phil Baron as Willio and Phillio.  They had regular gigs on television, radio and comedy clubs and universities throughout the US. Ryan and Baron later paired up again voicing characters of best friends Teddy Ruxpin (Baron) and Grubby the Octopede (Ryan) in the Teddy Ruxpin book and tape series as well as the 1987 television show The Adventures of Teddy Ruxpin.

The Willio and Phillio act brought Ryan back into music and after moving to California, he began to write and record songs for Disney. He provided the voice of Rabbit, Tigger, and Eeyore in the Disney Channel's long-running series Welcome to Pooh Corner and in many other Pooh cartoons. He also provided the voice of Barnaby the Dog on the popular series Dumbo's Circus.
