How to Write an Internship Cover Letter (With a Template)

Staring at a blank cover letter box is its own special kind of stress. You're supposed to sound professional but not stiff, confident but not arrogant, and somehow make a stranger care about you in a few paragraphs. So most people do the same thing: find a template, swap in the company name, and hope.

The good news is that this is exactly why a decent cover letter stands out. When most of the letters in the pile are the same letter with a different logo, yours only has to be specific to win.

What the reader actually wants to know

Whoever reads internship cover letters is usually reading a lot of them. They're trying to answer three things quickly:

1. Do you actually want this role, or are you applying everywhere?
2. Is there one real reason to believe you can do the work?
3. Can you write clearly?

Answer those in under 300 words and you're ahead of most of the stack. Nobody has ever turned down an intern because their cover letter was too short.

The structure

Paragraph one: why this role, at this company. One or two sentences. Name something specific: a product, a team, a project they've talked about, something in the posting itself. "I admire your innovative culture" reads like a template because it is one.

Paragraph two: one thing you've done that proves you can do the work. Pick your single most relevant project, job or class, and say what you did and what came of it. It's tempting to list everything. Don't. One strong example is more convincing than five mentioned in passing.

Paragraph three: the close. One sentence on what you'd bring, one on when you're available, and a thank-you. Done.

The template

Dear [Name, or "Hiring Team" if you can't find one],

I'm applying for the [Role] internship because [one specific thing about the company, team or posting that genuinely interests you]. [One sentence connecting it to what you want to learn or work on.]

[Your most relevant project, job or class]: [what you did, in one or two sentences, with the tools or methods you used]. [What came of it: a result, a number, what you learned, or who used it.] I'd bring the same [skill] to [something named in the posting].

I'm available [dates or term], and I'd love to talk about how I could help the team. Thank you for considering my application.

[Your name] [Email] · [Phone] · [Portfolio or LinkedIn]

A before and after

Before: "I am a hardworking and passionate student who would be a great fit for your company. I have strong communication skills and a proven ability to work in a team."

After, for example: "Last semester I built a budgeting dashboard in Python for our student government, which the treasurer now uses to track spending across 14 clubs. Your posting mentions internal analytics tools, and that's exactly the kind of work I want to do more of."

Fewer adjectives, more evidence. That's almost always the right trade.

Mistakes that quietly cost you

• Repeating your résumé. The letter should add the why, not re-list the what.
• Starting with "My name is". Your name's at the bottom. Open with the reason you're writing.
• The wrong company name. Read it twice. It happens way more than anyone admits.
• Going over 400 words. If you have to scroll, cut it.
• Apologizing for inexperience. Skip "Although I don't have much experience." Lead with what you do have. See How to Get an Internship With No Experience.

Should you write one if it's optional?

If you have a real reason to want the role, write a short one. It's one of the few places you get to explain yourself in your own words. If you'd only be filling the box with generic sentences, a strong résumé alone beats a weak letter next to it.
