No. You will receive your boarding pass from the airline after you have checked in (online).
If you are checking in online, then you will receive your boarding pass digitally (via email, mobile app, Apple Wallet, etc.). You can print out your boarding pass or you can present your boarding pass digitally to the staff at the airport.
You can often check in online within 24 hours before departure.
ATTENTION: Some airlines require a printed version of your boarding pass (example: Ryanair). You can find specific information on the website of your airline.
