What was McDonald's original corporate name when Ray Kroc incorporated it in 1955?

McDonald's original corporate name when Ray Kroc incorporated it in 1955 was McDonald's System, Inc.

Ray Kroc incorporated the business as McDonald's System, Inc., reflecting the operating and franchising system he was developing around the McDonald brothers' restaurant model. The company later became known as McDonald's Corporation, the name associated with the modern global business.

The early corporate name highlights that Kroc's expansion strategy was based on consistency: restaurant procedures, equipment, menus, service, and branding were intended to work in the same way across franchised locations.

A common error is to answer “McDonald's Corporation,” because that is the familiar present-day corporate name. The question concerns the 1955 incorporation, when the company was formally called McDonald's System, Inc.
