  The Cosmic Evolution Early Release Science Survey (CEERS), targeting the
Extended Groth Strip extragalactic field, is one of the JWST Director's
Discretionary Early Release Science programs. To date, all observations have
been executed and include NIRCam/MIRI imaging and NIRSpec/NIRCam spectroscopic
exposures. Here, we discuss the MIRI imaging, which includes eight pointings,
four of which provide deep imaging with the bluer bands (F560W, F770W) and four
with contiguous wavelength coverage in F1000W, F1280W, F1500W, and F1800W,
where two of these also include coverage in F770W and F2100W. We present a
summary of the data, the data quality, and data reduction. The data reduction
is based on the JWST Calibration Pipeline combined with custom modifications
and additional steps designed to enhance the output quality, including
improvements in astrometry and the removal of detector artifacts. We estimate
the image depth of the reduced mosaics, and show that these generally agree
with expectations from the Exposure Time Calculator. We compare the MIRI F560W
and F770W flux densities for bright sources to measurements from Spitzer/IRAC
Ch3 (5.8 $\mu$m) and Ch4 (8.0 $\mu$m), and we find that they agree with
systematic differences of $<0.1$ mag. For the redder MIRI bands, we assess
their quality by studying the spectral energy distributions (SEDs) of Galactic
stars. The SEDs are consistent with the expected Rayleigh-Jeans law with a
deviation $\sim 0.03$ mag, indicating that the MIRI colors are reliable. We
also discuss all publicly released data products (images and source catalogs),
which are available on the CEERS website (https://ceers.github.io/).
