+## Summary
+
+This RFC proposes the addition of a Progress component to the Open UI Design System. Progress components are used to represent the completion status of a task or process.
+
+# Basic Example
+
+```html
+<!-- Determinate Example -->
+<label for="progress">Example Label:</label>
+<oui-progress id="progress" value="20" max="100"></oui-progress>
+
+<!-- Indeterminate Example -->
+<label for="indeterminate-progress">Example Label:</label>
+<oui-progress id="indeterminate-progress"></oui-progress>
+```
+
+# Motivation
+
+Progress indicators are a common UI pattern used to communicate the status of a task or process to users. By providing a Progress component in the Open UI Design System, we can ensure a consistent and accessible implementation across applications.
+
+# Detailed Proposal
+
+The `oui-progress` component will provide a versatile, accessible, and themable implementation of progress indicators. The component will support both determinate and indeterminate modes.
+
+## API
+
+This component will be form associated so it can be labeled by a `<label>` element.
+
+### CSS States
+
+| State | Description |
+|-------|-------------|
+| `indeterminate` | The progress bar is in an indeterminate state. |
+
+### CSS Parts
+
+| Part    | Description                                |
+|---------|--------------------------------------------|
+| `track` | The track for the progress bar.            |
+| `fill`  | The filled in portion of the progress bar. |
+
+### Properties
+
+| Property | Type | Default | Readonly | Description |
+|----------|------|---------|-------------|
+| `value`  | Number | `0` | false | The current progress value. |
+| `max`    | Number | `100` | false |The maximum progress value. |
+| `position` | Number | `-1` | true | The current position of the progress bar. |
+
+### Attributes
+
+| Property | Description |
+|----------|------|---------|-------------|
+| `value`  | The current progress value. |
+| `max`    | The maximum progress value. |
+
+### Slots
+
+| Slot | Description                                                       |
+|------|-------------------------------------------------------------------|
+| `default` | Fallback text to render if the component otherwise fails to load. |
+
+### Events
+
+None
+
+## Accessibility
+
+The `oui-progress` component will be exposed using the `progressbar` role.
+
+The min (always 0) and max values will be exposed via `aria-valuemin` and `aria-valuemax` values (respectively).
+The current value will be exposed via `aria-valuenow`.
