Should I tell my interviewer that I stutter?

Should I tell my interviewer that I stutter? ​ I have an interview for an animal shelter volunteering program soon and I am extremely anxious that I am going to have several speech blocks and look like a fool. This is my first interview as well so I'm worried that the anxiety will get to me. I'm not sure if I should tell my interviewer that I stutter because I'm scared it will cost me the internship but at the same time, I want to warn them first in case I am unable to speak well. Any advice would be appreciated. Thank you!
