In [[computer programming]], a '''logic error'''  is a [[Software bug|bug]] in a program that causes it to operate incorrectly, but not to terminate abnormally (or [[crash (computing)|crash]]).<ref>{{cite book |last1=Breedlove |first1=Todd W. |last2=Albert |first2=Randal L. |title=C++: An Active Learning Approach |date=22 October 2010 |publisher=Jones & Bartlett Publishers |isbn=978-1-4496-1283-2 |page=44 |url=https://books.google.com/books?id=FgnnQ8Gqx1wC&pg=PA44 |access-date=20 March 2025 |language=en}}</ref> A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.

Logic errors occur in both [[Compiler|compiled]] and [[Interpreter (computing)|interpreted]] languages. Unlike a program with a [[syntax error]], a program with a logic error is a valid program in the language, though it does not behave as intended. Often the only clue to the existence of logic errors is the production of wrong solutions, though [[Static program analysis|static analysis]] may sometimes spot them.
