This is a list of unnumbered trans-Neptunian objects (TNOs) first observed since 1993 and grouped by the year of principal provisional designation. The data is sourced from the Minor Planet Center's (MPC) ''List of Trans Neptunian Objects'', ''List Of Centaurs and Scattered-Disk Objects'', ''List Of Other Unusual Objects'', and ''Database Search''.<ref name="MPC-List-TNOs" /><ref name="MPC-List-Cen-and-SDO" /><ref name="MPC-List-Unusual"/><ref name="MPC-a30.1"/> These objects will eventually be numbered as secured discoveries with an official discoverer determined by the MPC. Until then, additional observations are needed to sufficiently decrease an object's orbital uncertainty. {{As of|2026|05}}, there are 4,969 unnumbered objects, defined here as minor planets with a semi-major axis larger than 30.1 AU (Neptune's average orbital distance from the Sun).

The list also contains information from "Johnston's Archive", such as an object's diameter, its dynamical class and binary status with the satellite's diameter, as well as its albedo, spectral taxonomy and B–R color index.<ref name="TNO-list-Johnstons" /> Members of the extreme trans-Neptunian objects (ESDOs, EDDOs and sednoids) – with a semi-major axis greater than 150 AU and perihelion greater than 30 AU – are also identified. {{clear|left}}
