Medinaceli (pronounced [meðinaˈθeli]) is a municipality and town in the province of Soria, in Castile and León, Spain.

[2]Situated at the confluence of the rivers Jalón and Arbujuelo, Medinaceli was the site of the Celtiberian town known as Occilis or Okilis.

The Toro Jubilo annually occurs in Medinaceli, in which crowds of participants taunt a bull with balls of burning tar or turpentine (called "pitch") attached to its horns.

The Convent of Saint Elizabeth (16th century) (Convento de Santa Isabel), which lies next to the church of San Martín, also stands in good condition.

The beaterio (house inhabited by lay sisters) of San Román (Saint Romanus) is in ruins; it may have previously been a synagogue.
