De Dietrich Bugatti refers colloquially to a number of early automobile designs by Ettore Bugatti, known as the Types 2 through 7. Importantly, the vehicle known as the Type 2 of 1901 was designed by Bugatti before he joined the automobile manufacturer Lorraine-Dietrich in Niederbronn, Alsace, Germany following its successful reception. Types 3-7 were produced for De Dietrich between 1902 and 1904.

The Type 2 was a prototype automobile designed and built by Ettore Bugatti in 1901 with financial support from a Count Gulinelli. It won an award at the Milan Trade Fair that year,^[1] and gained the notice of Baron Adrien de Turckheim, managing director of the Lorraine-Dietrich automobile factory in Niederbronn in the then-German Alsace.

Types 3,4, and 5 were Bugatti's initial works for De Dietrich.^{[2][3][4][5][6][7][8][9][10][11]}
