BSP – United Left (Bulgarian: БСП – обединена левица, romanized: BSP – Obedinena Levitsa), formerly BSP for Bulgaria (Bulgarian: БСП за България, romanized: BSP za Bŭlgariya) until 2024, is a centre-left electoral alliance in Bulgaria led by the Bulgarian Socialist Party.

A big tent of the democratic socialist left, it is a coalition of social-democratic, communist and left-wing nationalist parties.

On European Union politics, the majority of its members hold pro-European views, while a minority hold more Eurosceptic stances.

The coalition has gone by multiple names since its foundation.
