The Mercedes-Benz W186 Model 300 was a four-door luxury sedan produced by Mercedes-Benz between 1951 and 1957. It was the company's flagship model at the time, succeeding the World War II era W150. Three versions were produced in succession, known informally as the 300a (or simply 300), 300b, and 300c. An enlarged "300d" variant built on the W189 chassis succeeded it in late 1957.

Also referred to as a "Type 300", the W186 was equal in features and price but superior in performance to the rival Rolls-Royce Silver Cloud and Bentley S1. Favored by statesmen and business leaders, it offered options such as a glass partition, VHF mobile telephone, and dictation machine.

The W186 is often identified as an Adenauer after Konrad Adenauer, the first Chancellor of the Federal Republic of Germany (West Germany), who employed six custom cabriolet, hardtop saloon, and landaulet versions of the W186 and its successor W189 during his 1949-1963 tenure. Among the custom features in these "parade cars" were writing desks, sirens, curtains, dividing partitions, sunroofs, and half-roof "landaulet" configurations.

Technologically advanced, the 300 was regarded as a "driver's" car, sharing numerous design innovations and mechanical components with the iconic Mercedes-Benz 300 SL "Gullwing", including engine, suspension, and chassis.

The four door 300 (W186) was introduced at the Frankfurt Motor Show in April 1951 and entered series production in November 1951. It had no "a" designation, which was informally added, along with the "b" and "c", by later enthusiasts seeking to distinguish the three W186 generations.

The Mercedes-Benz W189 model 300 was a four-door luxury tourer produced by Mercedes-Benz between 1957 and 1962. It was the company's flagship model at the time, equivalent to the modern S-Class and Maybach.

Marketed as the Type 300d, it was equal in features and price but superior in performance to the rival Rolls-Royce Silver Cloud. Favored by statesmen and business leaders, it offered options such as a glass partition, VHF mobile telephone, and dictation machine.

All but hand-built as the company flagship, the 300d is often colloquially referred to as the Adenauer, after Konrad Adenauer, the first Chancellor of Germany (then West Germany) who employed six custom cabriolet, hardtop saloon, and landaulet versions of the W189 and its precursor W186 series during his tenure. Among the custom features in these "parade cars" were writing desks, sirens, curtains, dividing partitions, sunroofs, and half-roof "landaulet" configurations.

Technologically advanced, the fuel injected 3.0 L inline-6 "Type 300" was regarded as a "driver's" car, sharing numerous design innovations and mechanical components with the iconic Mercedes-Benz 300 SL "Gullwing", including engine, suspension, and chassis. It was succeeded by the 6 L W100 Mercedes-Benz 600 Grosser Mercedes in 1963.
