Interfaces in TypeScript are used to define a structure for an object or a class. They provide strong type checking and help ensure consistency across your codebase. Interfaces can be used for classes, objects, functions, or even primitive values. To create an interface, use the keyword 'interface' followed by its name and a curly brace containing the interface properties. For example:

```typescript
interface Person {
firstName: string;
lastName: string;
age: number;
}

const person: Person = {
firstName: 'John',
lastName: 'Doe',
age: 30
};
```
