A lapel pin, also known as an enamel pin, is a small pin worn on clothing, often on the lapel of a jacket, attached to a bag, or displayed on a piece of fabric. Lapel pins can be ornamental or can indicate the wearer's affiliation with an organization or cause. Before the popularity of wearing lapel pins, boutonnières were worn.
 Lapel pins are frequently used as symbols of achievement and belonging in different organizations. Lapel pins from the organization are often collected by members and non-members alike.
 Businesses, corporates, & political parties also use lapel pins to designate achievement and membership. Lapel pins are a common element of employee recognition programs, and they are presented to individuals as a symbol of an accomplishment. Like fraternity and sorority pins, these lapel pins instill a sense of belonging to an elite group of performers at the organization. Businesses also award lapel pins to employees more frequently to boost employee morale, productivity, and employee engagement.

 In the USSR and the People's Republic of China, the prominent lapel pins with portraits of Lenin and Mao Zedong, respectively, were worn by youth as well as by Communist party members or people who felt like showing their official political credo. In Czechoslovakia, the Mao badges/pins were worn in the late 1960s and early 1970s by non-conformist youth as a prank and a way to provoke the "normalisationist" reactionaries of the purged post-1968 Communist Party of Czechoslovakia.

 Politicians in the United States often wear American flag lapel pins, especially after the attacks of September 11, 2001. By 2008, the flag pin had become "the quickest sartorial method for a politician to telegraph his or her patriotism." The practice declined somewhat in the following decade.
 Almost all manufacturing is currently done in China, specifically in and around Kunshan, a satellite city in the greater Suzhou region that is administratively at the county-level in southeast Jiangsu, China, just outside Shanghai. Inexpensive labor in China has made non-Chinese production of lapel pins few and far between. There are still multiple online shops run by people outside of China who make and sell lapel pins.
 In the die struck manufacturing process, there are five basic types of pins: Cloisonné, soft enamel, photo etched, screen printed and 4-color printed.

In the case of cloisonne and soft enamel, the shape and the design are stamped out.
