A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. Other shapes than rectangular may also be used. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands.

In some places, it is possible to send them for a lower fee than for a letter. Stamp collectors distinguish between postcards (which require a stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed by a private company, individual or organization, a postal card is issued by the relevant postal authority.

The world's oldest postcard was sent in 1840 to the writer Theodore Hook from Fulham in London, England. The study and collecting of postcards is termed deltiology.

In Japan, official postcards have one side dedicated exclusively to the address, and the other side for the content, though commemorative picture postcards and private picture postcards also exist. In Japan today, two particular idiosyncratic postcard customs exist: New Year's Day postcards (年賀状 nengajō?) and return postcards (往復はがき ōfuku-hagaki?). New Year's Day postcards serve as greeting cards, similar to Western Christmas cards, while return postcards function similarly to a self-addressed stamped envelope, allowing one to receive a reply without burdening the addressee with postage fees. Return postcards consist of a single double-size sheet, and cost double the price of a usual postcard – one addresses and writes one half as a usual postcard, writes one's own address on the return card, leaving the other side blank for the reply, then folds and sends. Return postcards are most frequently encountered by non-Japanese in the context of making reservations at certain locations that only accept reservations by return postcard, notably at Saihō-ji (moss temple). For overseas purposes, an international reply coupon is used instead.

In Japan, official postcards were introduced in December 1873, shortly after stamps were introduced to Japan. Return postcards were introduced in 1885, sealed postcards in 1900, and private postcards were allowed from 1900.

The United States Postal Service defines a postcard as: rectangular, at least 3 1⁄2 inches (88.9 mm) high × 5 inches (127 mm) long × 0.007 inches (0.178 mm) thick and no more than 4 1⁄4 inches (108 mm) high × 6 inches (152.4 mm) long × 0.016 inches (0.406 mm) thick. However, some postcards have deviated from this (for example, shaped postcards).

Traveling Postcards is a healing arts workshop, a tool for self-expression and a bridge that unites communities of women and men who care about women’s human rights.

Traveling Postcards creates a non threatening opportunity for personal connection to humanitarian issues that may seem overwhelming or geographically separate from our own lives. By providing personal connection, we create the possibility for every individual to become socially active in her community in a way that utilizes her best self.
