The Munich Radio Orchestra (German: Münchner Rundfunkorchester) is a German symphony orchestra based in Munich. It is one of the two orchestras affiliated with the Bavarian Radio (Bayerischer Rundfunk), the other being the Bavarian Radio Symphony Orchestra.

A precursor ensemble to the Munich Radio Orchestra was established in the 1920's. The current Munich Radio Orchestra was formalised in 1952, with Werner Schmidt-Boelke as its first chief conductor. The orchestra's focus has historically been on light music, with particular emphasis in its early years as an orchestra for operettas. The orchestra was also historically known for its Sunday concerts.

From the chief conductorship of Lamberto Gardelli (1982-1985) onwards, the orchestra expanded its repertoire into opera, specifically Italian opera. This work continued under the orchestra's next 3 chief conductors, all Italians, Giuseppe Patanè (1988–1989), Roberto Abbado (1992–1998), and Marcello Viotti (1998–2005). This activity extended to commercial recordings of operas and opera excerpts with the orchestra's chief conductors.

The orchestra faced budget constraints and the threat of dissolution by Bavarian Radio in 2004. In protest at these threats to the existence of the orchestra, Viotti resigned as chief conductor that year. After negotiations, the orchestra was preserved, with a reduction in size from 72 to 50 musicians.

Since September 2006, the orchestra's chief conductor is Ulf Schirmer. Schirmer has conducted commercial recordings for the Bavarian Radio's own BR-Klassik label, including Karl Amadeus Hartmann's "Des Simplicius Simplicissimus Jugend". The orchestra has also recorded for other labels such as EMI, CPO, RCA, Acanta and Sony Classical.
