3C 249.1 is a Seyfert galaxy located in the constellation Draco. It hosts a powerful radio source and is located at redshift 0.3115, with a peculiar radio structure. One of its radio lobes is classified as having a Fanaroff-Riley classification Type II, while the other lobe has no features nor containing hotspots.

3C 249.1 contains emission lines with an extended emission-line region. Its black hole is known to have a high accretion rate.

The star formation rate in 3C 249.1 is estimated to be between ranges of ∼1-250 M⊙ yr, according to researchers using spectral energy distributions, as well as high resolution mid-infrared spectra of quasars from the Palomar-Green sample.
