Naissus was an ancient city and former bishopric in Balkanic Dacia, which remains a Latin Catholic titular see.

History 
Naissus, today's Niš in Serbia, was important enough in the Roman province of Dacia Mediterranea to become an episcopal see at an early date and was a suffragan of the Metropolitan see in the Archdiocese of Sardica, in the sway of the Patriarchate of Constantinople.

The city was wrecked by Attila's Huns, but rebuilt, as the revival of the bishopric attests.

Residential bishops 
The names of several of early Suffragan Bishops of Naissus are known:
 Cyriacus (first half of the 4th century), sympathized with the heresy Arianism and opposed Marcellus of Ancyra
 Gaudentius (from before 343/344, apparently succeeding the former), till after 351, when he attended the council at Sirmium
 Bonosus (mentioned c. 380), who was deposed
 Martianus (before 409 to after 414), appointed by Pope Innocent I instead of the former
 Dalmatius (mentioned 451), allegedly signator in 458 of the letter of the bishops to Byzantine emperor Leo I the Thracian after the lynching by Coptic mobs of the Patriarch Proterius of Alexandria
 Gaianus (mentioned 516), invited to Constantinople by Byzantine Emperor Anastasius I Dicorus
 Proiectus, participant at the Ecumenical Second Council of Constantinople in 553 (which  repudiated the Three Chapters as Nestorian, condemned Origen of Alexandria and decreed the Theopaschite Formula).

Titular see 
It is listed by the Catholic Church as a Latin titular see  since the diocese was nominally restored in 1933 as Titular bishopric of Naissus (Latin) / Naisso (Curiate Italian) / Naissitan(us) (Latin adjective).

It has had the following incumbents, of the fitting Episcopal (lowest) rank, with a few archiepiscopal exceptions:
