Star cartography, stellar cartography, celestial cartography, or uranography (Koine Greek ουρανος [IPA: uːra'nos], "sky, heaven" + γραφειν [IPA: gra'pʰiːn] "write") is the branch of astronomy concerned with mapping the stars, galaxies, and a multitude of other celestial bodies. Positioning and measuring the light of charted objects requires a multitude of instruments, that have developed from bare-eye angle measurements with quadrants, later lenses for light magnification have been combined into sextants, and in the current age, computer automated space telescopes have been measuring up accurate star positions. Uranographers have historically produced planetary position tables, star tables and star maps fit for amateur and professional observations, nowadays computerized star maps, and automated positioning of telescopes are routinely using huge databases of stars and other astronomical objects.

A determining fact source for drawing star charts are naturally star tables. This is apparent when comparing the imaginative "star maps" of Poeticon Astronomicon – illustrations beside a narrative text from the antiquity – to the star maps of Johann Bayer based on precise star position measurements from the Rudolphine Tables by Tycho Brahe.

The term Stellar cartography was used in Star Trek: The Next Generation as the name of a department aboard the Starship Enterprise-D. It was also used in Star Trek:Voyager as the name of the department aboard the Starship Voyager. In both cases, the department was a subsection of the ship's science department, and, as the name would suggest, its responsibilities include charting previously-uncharted regions of space as the ship passes through them, as well as operating the ship's astrometrics lab(s); in practice, at least on Voyager, this meant that Stellar Cartography was responsible for all sensor data collection and analysis other than for ship operations (navigation, cursory ship/planet scans, transporter operation, etc.) or combat.
