PPPD is the Point-to-Point Protocol () which is used to manage network connections between two nodes on Unix-like operating systems. It is configured using command-line arguments and configuration files.

While it has initially been used to manage only dial-up access, it is also used to manage broadband connections such as DSL, if Point-to-Point Protocol over Ethernet () or Point-to-Point Protocol over ATM (PPPoA) is used.

The role of pppd is managing PPP session establishment and session termination.
