The Bezirksliga Oberbayern-Ost (English: District league Upper Bavaria-East) is currently the seventh tier of the German football league system in the eastern part of the Bavarian Regierungsbezirk of Upper Bavaria (German: Oberbayern).

[1][2] In 1988, when the Bezirksoberligas were introduced, the league lost some of its status as it was relegated one tier.

[1] With the league reform at the end of the 2011–12 season, which included an expansion of the number of Landesligas from three to five, the Bezirksoberligas were disbanded.

The runners-up of the Bezirksligas in Upper Bavaria would take part in a promotion round with the best-placed Bezirksoberliga team which did finish on a relegation rank to determine one or more additional promotion spots, depending on availability.

The Bezirksliga Oberbayern-Ost is fed by the following Kreisligas: Since 1995, the league has generally operated with a strength of 16 clubs and rarely deviated from this.
