Transmission Control Protocol (TCP) is an Internet standard transport layer protocol. It is connection-oriented and stream-oriented, as opposed to UserDatagramProtocol (UDP).

Most commonly found as the "TCP/IP Protocol Suite" - TransmissionControlProtocol over InternetProtocol. This is a common shorthand which refers to the suite of transport and application protocols which run over IP.
