Autograph collecting is the practice of collecting autographs of famous persons. Some of the most popular categories of autograph subjects are presidents, military soldiers, athletes, movie stars, artists, social and religious leaders, scientists, astronauts, and authors.

Some collectors may specialize in specific fields (such as Nobel Prize winners) or general topics (military leaders participating in World War I) or specific documents (e.g., signers of the Charter of the United Nations; signers of the U.S. Constitution; signers of the Israeli Declaration of Independence; signers of the Charter of the European Common Union; signers of the World War II German or Japanese surrender documents).

The collection of autographs may be in decline with fans preferring selfies instead.
