Caletricus (also known as Calétric, Chaletricus, or Chalactericus; French: Caltry) served as bishop of Chartres in the Frankish kingdom of Gaul during the latter half of the sixth century. He succeeded Lubin of Chartres, whose tenure is last documented in 551, and held the see for a period of more than twenty years. Caletricus died before 573, the year in which his own successor Pappolus is recorded attending a council in Paris. The poet Venantius Fortunatus, a near-contemporary, notes that Caletricus died at the age of thirty-eight.
The principal contemporaneous evidence for Caletricus consists of his subscription at two Frankish church councils: one held in Paris at some point between 557 and 563, and the Council of Tours in 567 or 568. His presence at these gatherings places him within the network of Frankish episcopal governance during the Merovingian period, when such councils served as the chief instrument of ecclesiastical discipline and legislative coordination across the Gaulish church. A ninth-century Life of Saint Lubin describes Caletricus, before his elevation, as a young priest of noble birth who had a sister named Mallegonde.
After his death, Caletricus was venerated locally in the Diocese of Chartres. His earthly remains were laid to rest beneath the altar of the church of Saint Nicholas in Chartres. During renovations to that church in 1703, his relics were rediscovered. He is commemorated on September 4 in the Roman calendar; the Diocese of Chartres also observed his feast on October 8. A representation of the bishop survives in a stained-glass lancet (bay 134) at Chartres Cathedral, attesting to his continued local veneration into the medieval period.
