This dataset provides a catalogue of young stellar groups identified in the solar neighbourhood using Gaia DR3 astrometric, photometric, and radial-velocity data. The member stars were selected from a young stellar object candidate sample and grouped with the HDBSCAN clustering algorithm in six-dimensional phase space. For each group, the catalogue includes the group identifier, median spatial position in Cartesian coordinates, median Galactic longitude and latitude, age and age uncertainty, intrinsic three-dimensional velocity dispersion and its uncertainty, group radius and radius uncertainty, and the number of member stars used for age fitting. Group centres and member counts were calculated using only stars retained in the age-fitting procedure. Groups with unreliable parameters were excluded from the final catalogue. This dataset can be used to study the spatial distribution, kinematics, size–velocity dispersion relation, and dynamical evolution of young stellar groups near the Sun.
