What is the name of Tesla's all-electric semi-truck unveiled in 2017?

Tesla’s all-electric semi-truck unveiled in 2017 is called the Tesla Semi.

Tesla presented a concept prototype at a press event on November 16, 2017. The vehicle was designed as a Class 8 tractor for long-haul freight, using battery-electric power instead of a conventional diesel engine. Tesla promoted lower operating costs, rapid charging through its planned Megacharger network, and a drivetrain warranty targeting one million miles.

At the unveiling, Tesla discussed two planned range versions—approximately 300 miles and 500 miles—and said production was expected to begin in 2019. Those launch projections changed as development continued, and customer deliveries eventually began later than originally announced. The truck’s name remained straightforward: “Semi,” referring to a semi-trailer tractor.

The Tesla Semi is not the same vehicle as the Tesla Roadster or Cybertruck. Nor are “Tesla Freight,” “Tesla Cargo,” and “Tesla Hauler” official model names. The Semi is Tesla’s dedicated heavy-duty commercial truck, intended for transporting trailers rather than passengers.
