Quick answer
Peak is the highest point of something (mountain peak, peak performance). Peek is a quick, often secretive look (take a peek). Pique means to stimulate or irritate (pique your curiosity).
Peak, peek and pique are homophones that trip up even confident writers, especially in the phrase “pique your interest,” which is very commonly misspelled as “peak your interest” or “peek your interest.” All three sound alike; none of them mean the same thing.
Quick Answer
Peak is a noun or verb about a highest point, literal (a mountain peak) or figurative (peak season). Peek is a noun or verb about a brief, often sneaky look. Pique is a verb meaning to arouse curiosity or interest, or occasionally to irritate someone.

Which Word Should I Use?
All three sound exactly the same, so you have to rely on meaning. Ask: am I talking about a high point (peak), a quick look (peek), or stirred-up interest or irritation (pique)? The single most common error is “peak your interest”, interest is always piqued, never peaked.
| Peak | Peek | Pique | |
|---|---|---|---|
| Meaning | Highest point | Quick, sneaky look | Arouse interest/irritation |
| Part of speech | Noun/verb | Noun/verb | Verb (rarely noun) |
| Example | Reached its peak. | Took a peek inside. | Piqued my curiosity. |
Common Mistakes
- “The trailer peaked my interest” should be “piqued my interest.”
- “Take a peak inside the box” should be “take a peek inside the box.”
- “Reached its peek” instead of “reached its peak.”
- Assuming pique always means irritation, its more common modern use is to spark curiosity.
