The chartoularios or chartularius (Greek: χαρτουλάριος), Anglicized as chartulary, was a late Roman and Byzantine administrative official, entrusted with administrative and fiscal duties, either as a subaltern official of a department or province or at the head of various independent bureaus.
The title derives from Latin chartulārius from charta (ultimately from Greek χάρτης chartēs), a term used for official documents, and is attested from 326, when chartularii were employed in the chanceries (scrinia) of the senior offices of the Roman state (the praetorian prefecture, the officium of the magister militum, etc.). Originally lowly clerks, by the 6th century they had risen in importance, to the extent that Peter the Patrician, when distinguishing between civil and military officials, calls the former chartoularikoi. From the 7th century on, chartoularioi could be either employed as heads of departments within a fiscal department (sekreton or logothesion), as heads of independent departments, or in the thematic (provincial) and tagmatic administration, although the occasional appointment of chartoularioi at the head of armies is also recorded. The ecclesiastic counterpart was called a chartophylax, and both terms were sometimes used interchangeably.
- The chartoularioi tou [oxeos] dromou (χαρτουλάριοι τοῦ [ὀξέος] δρόμου, "chartularies of the course"), subaltern officials in the department of the dromos ("the Course") under the logothetēs tou dromou.
- The so-called chartoularioi megaloi tou sekretou (χαρτουλάριοι μεγάλοι τοῦ σεκρέτου, "grand chartularies of the department"), as heads of the various bureaus of the department of the genikon ("the General [Fisc]"), and the chartoularioi tōn arklōn (χαρτουλάριοι τῶν ἀρκλῶν) or exō chartoularioi (ἔξω χαρτουλάριοι, "outer chartularies") as the senior treasury officials posted in the provinces ("outer" meaning outside Constantinople).
- The chartoularios tou oikistikou (χαρτουλάριος τοῦ οἰκιστικοῦ) or simply ho oikistikos, whose precise functions are unknown, is also attested under the genikon; it did become an independent bureau by the 11th century, but disappears after that. It is recorded that he was in charge of tax exemptions, and had various juridical duties in some themata in the 11th century; the office may have been associated with the imperial domains (oikoi).

A further chartoularios, in charge of the large army encampment (aplēkton) at Malagina (χαρτουλάριος τῶν Μαλαγίνων), was subordinated to him.
