The Mercedes-Benz O405 was a highly successful single-decker bus manufactured by Mercedes-Benz from the mid-1980s to the early 2000s as either an integral bus or a bus chassis and was the last VöV SL-II standard bus in production. It was the replacement for the Mercedes-Benz O305 and was widely used in Europe, the United Kingdom, Australia and Singapore.

The step-entrance version was known as the O405. A 3-axle articulated version was also built known as O405G. There were two generations of O405, designated as O405 MkI and O405 MkII. Most of them have their boxy roof dome (slightly arched) with a double-curvature windscreen, separately mounted destination indicator and pantograph system windshield wipers that was used on some buses such as the Dennis Dart, Leyland Lynx, MAN NL262 and the MAN SL202.

The O405 MkI was marketed between mid-1980s and early 1990s. It featured a Mercedes Benz OM447h naturally aspirated engine with outputs of either 157kW (210hp) or 184 kW (250 hp). Optionally available was a naturally aspirated compressed natural gas (CNG) engine model M447hG with 150 kW (205 hp) output. The gearbox coupled to the engine was usually the Mercedes-Benz W3E110/2.2R or Mercedes-Benz W3E112/2.2R (the former being able to handle the more powerful 184 kW engine), although there have been other gearboxes such as the ZF 5HP 500 or Allison B300R coupled to the engine.

The O405 MkII was marketed from the early 1990s to the late 1990s and into the early 2000s in some parts of the world. It featured a Mercedes-Benz OM447hA turbocharged engine with an output of 184 kW (250 hp), although some examples feature either a naturally aspirated engine (OM447h-II), a turbocharged engine (OM447hA) or a turbocharged, intercooled engine (OM447hLA). The gearbox coupled to the engine was either the ZF 4HP 500 or 5HP 500, or the Voith D864.3.
