Pedro López de Monforte (Latin: Petrus Lupi; floruit 1103–35) was an Iberian nobleman and castellan, probably originally from the Rioja.
[3] A certain "countess Sancha" (Santia comitissa) made a donation to the monastery of San Salvador de Oña on 19 December 1135 along with her sister Estefanía and brother Rodrigo Gómez.
[10] Between 1129 and 1133 Pedro sporadically held other tenencias from the crown, such as: Ferrino,[11] Mayorga,[12] Río Seco,[13] Salamanca,[14] and Gatón.
[15] Pedro was atop the list of confirmants in at least three royal charters in these years, indicating his high status at the court of Alfonso VII.
The Archbishop of Toledo, Raymond de Sauvetât, accused him of being "altogether unsuitable" (absolute simplex) and having granted church benefices to his supporters.
