Also called: lockup, lock-up period
In one line
A set time after an IPO (often around 180 days) during which employees and insiders are barred from selling their shares.
In plain English
When a company goes public, insiders usually can't sell straight away. A lock-up holds them back for a few months to avoid flooding the market, after which they're free to trade.

Why it matters when you sell
Even after an IPO, a lock-up delays your cash-out — and the price can move a lot before it lifts. It matters when you weigh selling privately now versus waiting.
