From Teflpedia

A contronym or contranym (both /kɒntrənɪm/) or auto-antonym is a word which is its own antonym. There are both homophonic contranym (homophones), and homographic contronyms (i.e. homographs).

Wiktionary has a list[1]

Fortunately for English language learners, in English they are pretty rare, and context should usually avoid ambiguity.
