We've compiled a list of appropriate messages, quotes and even a poem you can include to show your spouse's father some love.

Whether he's your future FIL or you've been part of the family for years, these thoughtful Father's Day messages for your father-in-law will serve up plenty of inspo.

In this article:

What to Write in Your FIL's Father's Day Card

There are several things to consider when deciding what to write in your father-in-law's Father's Day card, like your relationship with him, his personality and how he likes to be celebrated. Thinking about how well you get along with your FIL is an excellent starting point when crafting your message. If you're still getting to know him, noting a characteristic or two you admire is a great place to begin—especially if you're feeling unsure. Alternatively, if you're super close, you can talk about a favorite memory you've shared or how much you appreciate your unique relationship.

You'll also want to consider his personality when composing your Happy Father's Day message for your father-in-law. If he's constantly cracking dad jokes or loves a good pun, you can definitely include a funny phrase or quote in your card. On the other hand, if he's a real softie who is always going in for a hug when he sees you, a heartfelt message may be the best approach. Don't forget to wish him well and let him know you appreciate him, just like you would if you were writing a birthday message for your father-in-law.
