⚡ Quick Meaning
A red herring is a false clue. It distracts you from the real answer, so you look in the wrong place.
The muddy footprints were a red herring: the dog had made them, not my brother.
🎭 Wait... Why a Fish?
The phrase names a fish, but you never need one. Smoked herring has a strong smell, and one way to picture it is a strong smell that grabs your nose and pulls you off the trail. The fish is not the point. The point is the wrong direction it sends you in.
🎬 Picture the Situation
Someone has hidden the class football, and Ana and Ben are on the case. Ana finds a sock on the stairs and runs after it, very excited.
Ben shakes his head. "That sock is a red herring. The ball is in the cupboard."

- a mystery, a quiz or a puzzle has a clue placed to mislead you
Keep the phrase for a false clue. A small problem that really is a problem is not a red herring.

💡 The OddLingo Trick
Imagine a strong smell that pulls your nose away from the trail, so the real trail goes cold. A red herring is any clue that smells strong enough to pull you off course.
🕵️ Where Did It Come From?
Nobody has confirmed where this phrase began. The explanations below are possibilities, not proven facts.
Phrase Finder links the phrase to an older saying, "neither fish, nor flesh, nor good red herring," and says its earliest uses are older than the sense of a false clue.
Phrase Finder also describes two possible stories for the false-clue sense. In the first, hunters are said to have dragged a smoked herring along a trail to train hounds to follow a scent. The site argues that this fits training better than misleading, and the story is unproven. In the second, a herring is left in a trunk as a deliberate trick on a servant. The site finds this one more convincing because it involves real trickery, but it is not proven either.
Whatever the start, the idea of a strong smell that pulls you off course fits the meaning well.
