The final survey will cover 100x1arcmin^2^ MUSE fields. Each MUSE-Wide pointing has a depth of one hour and hence targets more extreme and more luminous objects over ten times the area of the MUSE-Deep fields (Bacon et al., 2017A&A...608A...1B). The legacy value of MUSE-Wide lies in providing "spectroscopy of everything" without photometric pre-selection. We describe the data reduction, post-processing and PSF characterization of the first 44 CANDELS/GOODS-S MUSE-Wide pointings released with this publication. Using a 3D matched filtering approach we detect 1602 emission line sources, including 479 Lyman-{alpha} (Lya) emitting galaxies with redshifts 2.9<~z<~6.3. We cross-matched the emission line sources to existing photometric catalogs, finding almost complete agreement in redshifts (photometric and spectroscopic) and stellar masses for our low redshift (z<1.5) emitters. At high redshift, we only find ~55% matches to photometric catalogs. We encounter a higher outlier rate and a systematic offset of {Delta}z~=0.2 when comparing our MUSE redshifts with photometric redshifts from the literature. Cross-matching the emission line sources with X-ray catalogs from the Chandra Deep Field South, we find 127 matches, mostly in agreement with the literature redshifts, including ten objects with no prior spectroscopic identification. Stacking X-ray images centered on our Lya emitters yields no signal; the Lya population is not dominated by even low luminosity AGN. Other cross-matches of our emission-line catalog to radio and submm data, yielded far lower numbers of matches, most of which already were covered by the X-ray catalog. A total of 9205 photometrically selected objects from the CANDELS survey lie in the MUSE-Wide footprint, of which we provide optimally extracted 1D spectra. We are able to determine the spectroscopic redshift of 98% of 772 photometrically selected galaxies brighter than 24th F775W magnitude. All the data in the first data release - datacubes, catalogs, extracted spectra, maps - are available on the website https://musewide.aip.de. Description: We provide four tables in addition to the material available at https://musewide.aip.de. Two of these tables relate to the photometrically selected objects from the CANDELS (Guo et al., 2013, Cat. J/ApJS/207/24) catalog that lie in the MUSE-Wide DR1 area. One simply lists all 9205 objects and their (possible) emission line counterpart, the other identifies the 772 objects brighter than 24th magnitude (F775W), asigns redshift and confidence to that identification and further links the object to the 3DHST (Skelton et al., 2014, Cat. J/ApJS/214/24) catalog. The other two tables relate to the emission line selection done with LSDCat (Herenz & Wisotzki, 2017A&A...602A.111H) on the MUSE-Wide DR1 footprint. One identifies the 1602 emission line objects, relates them to photometric catalogs and provides stellar masses if there is a photometric match. The other lists emission line properties such as flux densities and kron radii of the 3057 individual emission lines.
