  We develop a parallel optically detected magnetic resonance (PODMR)
spectrometer to address, manipulate and read out an array of single
nitrogen-vacancy (NV) centers in diamond in parallel. In this spectrometer, we
use an array of micro-lens to generate 20 * 20 laser-spot lattice (LSL) on the
objective focal plane, and then align the LSL with an array of single NV
centers. The quantum states of NV centers are manipulated by a uniform
microwave field from a {\Omega}-shape coplanar coil. As an experimental
demonstration, we observe 80 NV centers in the field of view. Among them,
magnetic resonance (MR) spectrums and Rabi oscillations of 18 NV centers along
the external magnetic field are measured in parallel. These results can be
directly used to realize parallel quantum sensing and multiple times speedup
compared with the confocal technique. Regarding the nanoscale MR technique,
PODMR will be crucial for high throughput single molecular MR spectrum and
imaging.
