Dr. Robinson is the name of two characters in the Tom Sawyer series:
- Dr. Robinson (Tom Sawyer) is a character from The Adventures of Tom Sawyer, He is one of the grave-robbers whom Tom and Huckleberry Finn spot exhuming a corpse; he is killed by Injun Joe.
- Dr. Robinson (Huckleberry Finn) is a also character from Adventures of Huckleberry Finn, the first person to cast doubt on the Duke and King for their impersonation of the brothers of the late Peter Wilks. Like the identically-named but much-younger character in the previous book, he is also involved in the exhuming of a corpse, although in this latter case it is completely legal; the townspeople want to examine the dead man's tattoos.
