We present images of IRAS 08235-4316 with the Dark Energy Camera Plane Survey (DECaPS; spanning 0.398-1.034 μm, at ∼1″ resolution) and the Submillimeter Array (SMA; at 1.38 mm (217 GHz) and ∼1$\mathop{.}\limits^{^{\prime\prime} }$9 × 1$\mathop{.}\limits^{^{\prime\prime} }$2 resolution), a young stellar object (YSO) located in the Vela constellation near to the Puppis boundary, detected in a systematic search for new large/extended emission sources. The DECaPS data show an asymmetric bipolar morphology with a large angular extent of ∼7$\mathop{.}\limits^{^{\prime\prime} }$1 separated by a dark lane, characteristic of highly inclined protoplanetary disks and less-evolved YSOs with outflows. The SMA data show an extended continuum structure along the optical dark lane with a smaller angular extent of ∼4$\mathop{.}\limits^{^{\prime\prime} }$6. The detected ¹²CO J = 2-1 emission tentatively shows a velocity gradient along the position angle of the dark lane/millimeter continuum, which may trace rotating gas. Additional ¹²CO emission is present, which could trace infalling/outflowing gas and/or a nearby gas cloud. We estimate a distance to IRAS 08235-4316 of at least ∼191 pc. Supported by additional spectral energy distribution modelling, we infer IRAS 08235-4316 to be a newly discovered Class I YSO with an outflow, host to an embedded protoplanetary disk, with a large millimeter radius of ∼440 au and dust mass ≳ 11 M_⊕.
