How Old Do You Need to Be to Join the Knights of Columbus
If you’ve been thinking about joining the Knights of Columbus, age is probably one of the first practical questions on your mind. The answer is straightforward, but there’s more to it than a single number. The organization has different membership tracks depending on your age, and knowing which one applies to you makes the whole process much smoother.
This article lays out the age requirements clearly, explains what each tier of membership looks like, and tells you exactly what to expect at each stage.
The Core Age Requirement for Full Membership
To join the Knights of Columbus as a full, dues-paying member, you must be at least 18 years old. You also need to be a practical Catholic man in good standing with the Church. Those two requirements work together. Age alone gets you in the door, but your faith and gender are equally part of the eligibility picture.
The 18-year minimum has been the standard for as long as most council leaders can remember. It aligns with the general threshold for adult status in the United States, and the Knights treat it as a firm line. A 17-year-old, even one who is an active and committed Catholic, will need to wait until his 18th birthday before a council can process his application for full membership.
Is There an Upper Age Limit?
There is no maximum age. A man who converts to Catholicism at 65 and meets all the other requirements can join tomorrow. I’ve personally heard of men in their 70s and 80s joining their local council for the first time, often after a family member encouraged them to look into it. The Knights welcome men at any life stage.
The Columbian Squires: Membership for Younger Catholics
For young Catholic men between the ages of 10 and 17, the Knights of Columbus sponsors a separate youth program called the Columbian Squires. This is the most direct pipeline into eventual full membership, and it’s a serious program in its own right.
The Columbian Squires operate in local “circles” that are typically sponsored by a Knights of Columbus council. Members participate in faith formation, community service, and leadership development. It prepares young men for the responsibilities that come with full membership later on.
Here’s a quick breakdown of the two primary membership tiers:
| Membership Tier | Age Range | Organization |
|---|---|---|
| Columbian Squires | 10 to 17 | Columbian Squires (K of C sponsored) |
| Full Knights Membership | 18 and older | Knights of Columbus |
If your son or a young man in your parish is interested in the Knights but hasn’t turned 18 yet, the Squires program is the right starting point. Many council leaders actively recruit from local Squires circles because those young men already understand the culture and mission of the organization.
What Happens When a Squire Turns 18?
The transition from Squire to full Knight is something councils handle case by case, but it’s generally a smooth process. A young man who has been active in his Squires circle and turns 18 can apply to his sponsoring council for full membership. His background in the Squires counts in his favor, both socially and practically.
He goes through the standard membership process, including the three degrees of initiation that every Knight experiences. His Squires history gives him a head start on understanding the organization’s values, but the formal degrees are still a requirement for full membership.

Other Eligibility Factors Worth Knowing
Age is the most concrete factor, but a complete picture of eligibility includes a few other points.
- You must be a Catholic man, 18 or older.
- You must be in good standing with the Catholic Church, meaning you practice your faith.
- You need a referral or application through a local council. There is a formal petition process.
- Two council members in good standing typically need to recommend your application, though some councils have slight variations in their process.
- You pay annual dues, which vary by council but generally fall in the range of $50 to $100 per year at the local level, plus a separate Supreme Council assessment.
The dues and recommendation requirements are worth knowing ahead of time so you go into the process prepared rather than surprised.
How to Find Your Local Council
Once you know you meet the age and faith requirements, the next step is finding a council near you. The Knights of Columbus website has a council locator tool. Your parish is also a reliable starting point. Most active parishes have at least one or two council members who can point you in the right direction, often within the same conversation.
I’d recommend asking your pastor if the parish has a Knights council directly associated with it. Many do. Those parish-based councils are often the most active and community-connected, and joining one puts you at the center of parish life in a way that general council membership sometimes doesn’t.
A Note on Associate Membership
Some councils offer an associate membership category for men who want to support the organization financially and spiritually but prefer a lower level of direct involvement. The age requirement for associate membership mirrors full membership at 18. It’s a smaller commitment, but the same door to entry applies.

Key Takeaways
To pull it all together, here is what you need to remember.
- Full membership in the Knights of Columbus requires you to be at least 18 years old.
- There is no upper age limit. Men of any age are welcome to join.
- Young Catholic men between 10 and 17 can participate through the Columbian Squires program.
- Squires who turn 18 can apply for full membership through their sponsoring council.
- Beyond age, you must be a practicing Catholic man in good standing with the Church.
If you’ve been on the fence about joining, the age question is settled. At 18, the door is open. Find your local council, introduce yourself, and ask about their petition process. The commitment is real, but so is the community you gain in return.
