Dengan pengumuman resmi film ini di San Diego Comic-Con 2019, it was promoted by Feige, Shortland, and cast members who introduced footage from the first 30 days of production.<ref name="SDCCDetails" /> The first teaser trailer for the film, featuring some of the footage that was shown at Comic-Con, was released on December 3, 2019.<ref name="TeaserCNN" /><ref name="TeaserVerge" /> Several commentators noted that the film was "long awaited" or "highly anticipated" by fans,<ref name="TeaserCNN" /><ref name="TeaserVerge" /><ref name="TeaserMS" /> and highlighted the spy thriller tone of the trailer.<ref name="TeaserMTV" /><ref name="TeaserForbes" /> Rachel Leishman of [[The Mary Sue]] described finally seeing the trailer for a ''Black Widow'' film as "surprisingly emotional", and felt that setting the film between ''Civil War'' and ''Infinity War'' would allow the character to grow into her more mature form from the latter film, after earlier MCU films had depicted the character in a supporting role to the male Avengers.<ref name="TeaserMS" /> Scott Mendelson at ''[[Forbes]]'' compared the trailer's story and tone to the films ''[[Atomic Blonde]]'' (2017), ''[[Red Sparrow]]'' (2018), and ''[[Anna (2019 film)|Anna]]'' (2019), but felt that starring a familiar character would give ''Black Widow'' a commercial advantage over those films. Mendelson thought that this aspect could outweigh the teaser's focus on "family melodrama" over superheroics, which he compared to ''[[Thor (film)|Thor]]'' (2011).<ref name="TeaserForbes" /> ''[[The Hollywood Reporter]]''{{'}}s Richard Newby highlighted what he found to be noticeable differences between Shortland's shot composition and cinematography in the trailer from the styles of [[Jon Favreau]], Joss Whedon, and the [[Russo brothers]], all directors who helped to define Black Widow in previous MCU films.<ref name="TeaserTHR" />
