Valpuesta (Latin Valliposita or Valle Conposita) was a Catholic diocese in Castile in northern Spain. Today it is a titular see.

According to unreliable documents in the cartularies of Valpuesta, the diocese was established in 804 as a suffragan of the Metropolitan Archdiocese of Tarragona. It was suppressed in 1087 and its territory merged into the then bishopric of Burgos (now a metropolitan Archdiocese).

The diocese was nominally revived in 1969 as a titular bishopric of the lowest (episcopal) rank.

It since has the following (near-)consecutive, so-far regular (not secular) incumbents, so far of the fitting Episcopal (lowest) rank:
