Short answer: yes. If you're a non-Jewish man (or in many congregations, a non-Jewish woman too) attending a bar or bat mitzvah, you wear a kippah inside the sanctuary. It's the expected sign of respect, not a religious claim. The synagogue almost always has a basket of them near the door.
The longer answer has a little nuance — Reform allows a few exceptions, Orthodox is stricter, and outside the sanctuary the rules relax — but the operating principle is simple. If you're under the roof of the synagogue during the service, you wear what the rabbi's wearing. Here's the full breakdown.
What a kippah actually is
A kippah (כיפה), also called a yarmulke in Yiddish, is a small head covering worn as a sign of awareness that there is something — God, tradition, mystery — above you. It's not a Torah-mandated commandment; it's a custom that hardened into a near-universal practice in observant Jewish life over the last several centuries.
The Hebrew root k-p-h means "dome." That's the geometry. A kippah is a literal dome between your head and the sky, marking the space above as different.
Wearing one is not a statement of faith. It's a statement of attentiveness to the room. Which is exactly why non-Jewish guests are welcome — and expected — to wear them in the sanctuary.
Is it appropriation? No.
This is the question most non-Jewish guests are actually anxious about, and the answer is unambiguous: no. Wearing a kippah at a bar mitzvah is the opposite of appropriation. It's the host community handing you a basket and saying, "here, this is how you show you're paying attention."
Jewish tradition specifically frames the kippah as something a non-Jew should wear inside a synagogue during a service. Refusing it would be the rude move, not wearing it. Compare to a guest at a Catholic funeral declining to stand when the casket processes — technically permitted, socially read as cold.
If anyone tells you otherwise — online or in person — they're wrong about this particular custom. The host family invited you, the synagogue provides the kippot for you, and the room expects you to wear one. For the broader guest playbook, see non-Jewish guest etiquette.
By denomination — what's actually expected
The expectation is consistent across denominations for men, and varies for women.
Orthodox synagogues. All men wear kippot in the sanctuary. No exceptions. Women cover their hair if married (typically a wide-brimmed hat or a more substantial covering); unmarried women generally don't cover. Non-Jewish women follow the same convention as the Jewish women in the room.
Conservative synagogues. All men wear kippot. Most adult women — Jewish and non-Jewish — also wear a kippah or a lace head covering, particularly if they're going up for an honor. Some Conservative women wear a tallit as well. A non-Jewish woman watching from the pews can usually go without head covering, but wearing one signals respect and is welcomed.
Reform synagogues. Kippot are universally available but not always universally worn. The rabbi will be wearing one; most men in the room will be wearing one; some won't. Reform is the only denomination where a non-Jewish man could plausibly sit through a service without one. Even so — if everyone around you is wearing a kippah, wear a kippah. Reading the room is the whole rule.
Reconstructionist. Treat like Conservative — kippot expected for men, common for women.

What about women's hair as a covering?
In Reform and many Conservative settings, the convention for women is "your hair counts as head covering" — meaning women aren't required to wear an additional kippah or scarf during the service. If you're a non-Jewish woman with hair, you can absolutely show up bareheaded in those settings and be entirely appropriate.
In Orthodox settings, married women cover their hair regardless of religion (it's a married-woman convention, not specifically Jewish). A non-Jewish married woman attending an Orthodox bar mitzvah should bring a scarf or hat that covers most of her hair. Single non-Jewish women don't need to cover.
Non-Jewish women who want to wear a kippah in Conservative or Reform settings are welcome to. Most synagogues now carry a smaller lace-style kippah specifically designed for women, often in a basket separate from the men's. It's a respectful choice and not a religious one.

Where to find one when you arrive
Almost every synagogue has a basket or rack of kippot in the lobby, by the sanctuary door, or in a small alcove near the coat check. Look for:
- A wicker basket on a small table near the entry
- A wooden rack with kippot hanging on dowels
- A side table with a sign that says "Kippot" or "Head Coverings"
If you can't find them, ask any usher or the person greeting at the door. The phrase is: "Where can I grab a kippah?" Nobody will be offended. Many guests ask this question; you're not the first.
Take one before you walk into the sanctuary. Put it on the top-back of your head — it doesn't need to cover the whole crown, just sit there. Most kippot have a built-in clip; if yours doesn't, you can press it gently to your hair. Bobby pins are sometimes available.
You keep it on through the service, through the kiddush luncheon, and you can remove it once you leave the synagogue building. If there's a kiddush brunch in the social hall, men generally keep them on through the meal. For more on the post-service meal, see what is a kiddush luncheon.
What about at the party that evening?
If the reception is at the synagogue, the kippah convention continues. If the reception is at a separate venue — hotel ballroom, mansion, restaurant — the kippah is optional and most guests don't wear one to the party. The bar mitzvah kid and the rabbi may still wear theirs; most guests don't.
The line is the synagogue building, not the event. Once you've left the sanctuary and gone to a different venue, you're a regular wedding-style guest. For what to wear to the party, see what to wear to a bar mitzvah by service type.
Common questions
Can I wear the kippah I took home from a previous bar mitzvah? Yes. Most families monogram them as favors. Wearing it shows you've been before and that you saved it. Lovely move.
Do I need to wear a kippah if I'm watching the service from outside the sanctuary on a livestream? No. The custom is tied to physical presence inside the sanctuary.
What if I'm seated but the kippah keeps falling off? Most synagogues have bobby pins at the basket. Ask. Or palm one in your pocket — you really only need it on when you're standing or walking.
Can I take one home? Almost always yes — many bar mitzvah families specifically order extra kippot embossed with the kid's name and date as favors. It's a souvenir; take one.
