  We present the discovery of a triplet of emission-line nuclei in the
disturbed disk galaxy NGC 3341, based on archival data from the Sloan Digital
Sky Survey and new observations from the Keck Observatory. This galaxy contains
two offset nuclei within or projected against its disk, at projected distances
of 5.1 and 8.4 kpc from its primary nucleus and at radial velocity separation
of less than 200 km/s from the primary. These appear to be either dwarf
ellipticals or the bulges of low-mass spirals whose disks have already been
stripped off while merging into the primary galaxy. The inner offset nucleus
has a Seyfert 2 spectrum and a stellar velocity dispersion of 70+/-7 km/s. The
outer offset nucleus has very weak emission lines consistent with a LINER
classification, and the primary nucleus has an emission-line spectrum close to
the boundary between LINER/HII composite systems and HII nuclei; both may
contain accreting massive black holes, but the optical classifications alone
are ambiguous. The detection of an offset active nucleus in NGC 3341 provides a
strong suggestion that black hole accretion episodes during minor mergers can
be triggered in the nuclei of dwarf secondary galaxies as well as in the
primary.
