Sweethearts (also known as conversation hearts) are small heart-shaped sugar candies sold around Valentine's Day. Each heart is printed with a message such as "Be Mine", "Kiss Me", "Call Me", "Let's Get Busy", or "Miss You". Sweethearts were made by the New England Confectionery Company, or Necco, before being purchased by the Spangler Candy Company in 2018. They were also previously made by the Stark Candy Company. Necco manufactured nearly 8 billion Sweethearts per year. Similar products are available from Brach's and other companies. A similar type of candy is sold in the UK under the name Love Hearts.

In the 1990s, Necco vice-president Walter Marshall wanted to update some of the sayings and retire others, including "Call me", "Email me", and "Fax me". The romantic expressions continue to be revised for young Americans. Necco received hundreds of suggestions a year on new sayings. Necco produced the hearts year-round, but mixing of colors and packaging were ramped up beginning in September to meet the demand for the product at Valentine's Day.

Sweethearts were made softer with vivid colors and new flavors. These new flavors included sour apple, strawberry, and "spring fresh."
