We present spectral classifications from optical spectroscopy of 263 massivestars in the north-eastern region of the Large Magellanic Cloud. The observedtwo-degree field includes the massive 30 Doradus star-forming region, theenvirons of SN1987A, and a number of star-forming complexes to the south of 30Dor. These are the first classifications for the majority (203) of the starsand include eleven double-lined spectroscopic binaries. The sample alsoincludes the first examples of early OC-type spectra (AAOmega 30 Dor 248 and280), distinguished by the weakness of their nitrogen spectra and by C IV 4658emission. We propose that these stars have relatively unprocessed CNOabundances compared to morphologically normal O-type stars, indicative of anearlier evolutionary phase. From analysis of observations obtained on twoconsecutive nights, we present radial-velocity estimates for 233 stars, findingone apparent single-lined binary and nine (>3sigma) outliers compared to thesystemic velocity; the latter objects could be runaway stars or large-amplitudebinary systems and further spectroscopy is required to investigate theirnature.
