Herbert Lawrence Block, commonly known as Herblock, was an American editorial cartoonist and author best known for his commentaries on national domestic and foreign policy.

An editorial cartoonist, also known as a political cartoonist, is an artist who draws editorial cartoons that contain some level of political or social commentary. Their cartoons are used to convey and question an aspect of daily news or current affairs in a national or international context. Political cartoonists generally adopt a caricaturist style of drawing, to capture the likeness of a politician or subject. They may also employ humor or satire to ridicule an individual or group, emphasize their point of view or comment on a particular event.
