This is a list of characters in the Nickelodeon animated series Mina and the Count.
- Mina Harper (voiced by Tara Strong): A seven-year-old human child with red long hair in a ponytail and red clothes. She likes to go to school and to play with her toys, and she doesn't get along with her sister Lucy. She meets the Count one night and they become best friends.
- Vlad the Count (voiced by Mark Hamill): A 700 year old immortal vampire with light blue skin and a blue cape and a black suit. In his past, he probably made a living drinking young women's blood. Thanks to Mina Harper, he represses his evil tendencies. He has many powers, including the abilities to transform into a bat or mist, use telekinesis, and to hypnotize people and animals to do his bidding. He finds comics and toys amusing (again, thanks to Mina Harper) and is very intelligent. He believes that "mortal food" is disgusting.
- Igor (voiced by Jeff Bennett): Count's Quasimodo-like servant who wears sandals and green clothes and always has a maniacal laugh.

In his free time, he likes to watch television.
- Nick Powell (voiced by Billy West): He is the school's bully and always hangs around with the twin boys.
