Weekend Marketplace is a block of infomercials that air on FOX on Saturday mornings. It is believed to be the first time a network has put infomercials (basically long commercials that look like a regular program) as part of its regular schedule.

Despite being aired by FOX, Weekend Marketplace does not carry the FOX branding, does not show the network's logo bug in the lower right corner, nor is any promotional advertising for network shows seen during the block. Weekend Marketplace is also not an official name for the block, but is only used as a placeholder title in local station listings, most of which list the block as four separate segments of infomercials to avoid confusion about the block's format. As a result, the Weekend Marketplace block resembles a segment of infomercials locally programmed by each FOX affiliate.

As of September 2014, Weekend Marketplace still airs on a number of FOX affiliates, although it has been replaced in other markets by Xploration Station, a syndicated children's educational programming block.
