Mind your own business — Used to tell someone to stop interfering in or asking about matters that do not concern them.
Meaning
“Mind your own business” is a direct expression used to tell someone that they are being too nosy, intrusive, or interfering, and that they should focus on their own affairs instead. It is typically said as a sharp response to an unwelcome question, comment, or piece of unsolicited advice about something personal, such as someone's relationship, finances, or private choices.
The phrase can be softened in tone with friends (“oh, mind your own business!” said jokingly) or delivered sharply as a firm boundary with a stranger or nosy acquaintance. It is a very common expression in everyday English and is understood by speakers of all ages and backgrounds.
Origin & Usage Note
The idiom combines two everyday words in a straightforward way: “mind” here means to pay attention to or take care of something, and “business” refers to one's personal affairs rather than commercial activity. Put together, the phrase instructs someone to pay attention to their own matters instead of someone else's. Unlike many idioms with a traceable historical anecdote, this expression seems to have simply grown out of ordinary usage over a long period, since the underlying meaning of the words is already transparent.
It remains one of the most recognisable and direct idiomatic phrases in English, appearing in everyday conversation, popular songs, and film dialogue. General dictionaries such as the Cambridge Dictionary list it as a standard fixed expression.

How to Use It
The idiom is most often used as a command (“mind your own business!”) directed at someone being intrusive, but it can also describe a habitual trait in the third person (“she minds her own business”), where it takes on a more positive, approving meaning of being discreet and non-nosy. As a direct command, it is informal and can sound rude; the descriptive use is more neutral and even complimentary.
