Square Asterisk

This icon represents required field indicators and mandatory input markers in form and data entry systems. Featuring an asterisk symbol contained within a square, this icon indicates required fields, mandatory data entry, and the important markers that distinguish essential inputs from optional form fields across web applications.

In form interfaces across web applications and registration systems, users encounter this icon marking required fields that must be completed before submission. CRM platforms like Salesforce and HubSpot implement it to indicate mandatory contact information, while checkout forms on e-commerce platforms display it for essential payment and shipping details requiring completion.

The asterisk symbol communicates more than simple notation - it specifically represents obligation, the validation requirements that prevent form submission if omitted, and the visual hierarchy that helps users prioritize which fields demand attention. This universal marker helps reduce form abandonment by clearly indicating requirements.

Square Asterisk is one of 1,655 icons in Lucide, made by Lucide Contributors and released under ISC. It is drawn on a 24 × 24 grid with a 2 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds SquareAsteriskIcon to components/icons/lucide-square-asterisk.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed SquareAsteriskIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Yes, if your project has lucide-react: Square Asterisk is `SquareAsteriskIcon` there, used as <SquareAsteriskIcon />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Square Asterisk icon, or any of 1,655 Lucide icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Square Asterisk is a line icon drawn with a stroke width of 2. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Square Asterisk", so screen readers say what it does.

Yes. SquareAsteriskIcon passes every SVG prop to the svg element, so <SquareAsteriskIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. ISC allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: ISC only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Lucide, Lucide Contributors and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
