Finding the right coincidence synonym can make your English more precise and natural. Common alternatives include chance, happenstance, accident, fluke, serendipity, synchronicity, fortuity, and chance occurrence. However, these words are not always interchangeable because each carries a slightly different meaning or tone.
For example, chance is a broad and everyday choice, while serendipity usually describes a fortunate or pleasant unexpected event. Happenstance emphasizes something occurring accidentally, while fluke often suggests an unusual or unlikely result.
Quick Answer: What Is a Synonym for Coincidence?
The best general synonym for coincidence is chance occurrence or simply chance. Depending on the context, you can also use happenstance, accident, fluke, serendipity, fortuity, synchronicity, concurrence, or chance event.
A coincidence happens when two or more events occur together or at the same time in a way that seems surprising, even though there may be no obvious connection between them.
Example:
“I met my old teacher at the airport by coincidence.”
You could say:
- “I met my old teacher at the airport by chance.”
- “Meeting my old teacher there was a strange coincidence.”
- “It was a remarkable piece of happenstance.”
- “Our meeting felt like synchronicity.”
The best replacement depends on whether you want to emphasize randomness, surprise, good fortune, unusual timing, or an apparent connection.
What Does Coincidence Mean?
A coincidence is a situation in which separate events happen at the same time or in a similar way unexpectedly.
The events may appear connected, but a coincidence does not necessarily mean that one event caused another.
Example:
“You and I were born on the same day. What a coincidence!”
The word is commonly used in everyday conversation when something unexpected seems unusually connected.
Coincidence in Simple English
In simple English, a coincidence is when two unrelated things happen in a surprising way at the same time or in a similar situation.
For example, imagine thinking about an old friend and then receiving a message from that person a few minutes later. You might call that a coincidence.

Coincidence vs. Chance
Coincidence and chance are closely related, but they are not always interchangeable.
Chance usually focuses on randomness or lack of control.
“I met her by chance.”
Coincidence focuses more on the surprising relationship between separate events.
“It was a coincidence that we both chose the same restaurant.”
A useful rule is:
Chance = randomness
Coincidence = surprising occurrence together
Coincidence vs. Happenstance
Happenstance describes something that happens accidentally or through circumstances rather than deliberate planning.
“Coincidence” often highlights the surprising relationship between events, while “happenstance” emphasizes accidental circumstances.
Example:
- “By coincidence, we both arrived at 8:00.”
- “By happenstance, we ended up working in the same office.”
Both can work, but the emphasis is slightly different.
Coincidence vs. Serendipity
These words are sometimes confused.
A coincidence does not have to be positive.
Example:
“It was a coincidence that both flights were delayed.”
Serendipity usually involves something beneficial, enjoyable, or valuable being discovered unexpectedly.
Example:
“Finding that rare book in a small shop was serendipity.”
Therefore:
Coincidence = unexpected similarity or timing
Serendipity = fortunate unexpected discovery or event
Coincidence vs. Synchronicity
Synchronicity is a more specialized term.
It is often used when two events appear meaningfully connected even though there is no obvious causal relationship between them.
For everyday English, coincidence is usually more natural.
Use synchronicity when discussing meaningful patterns, personal experiences, psychology, spirituality, or philosophical ideas.
Coincidence vs. Fluke
A fluke usually describes an unexpected and unusual result, often one that seems unlikely to happen again.
Example:
“His victory was a fluke.”
This can sometimes sound dismissive because it may suggest that the person succeeded mainly through luck.
A coincidence, on the other hand, is not necessarily negative or dismissive.
How to Choose the Right Coincidence Synonym
The best synonym depends on what you want to emphasize.
For Everyday Conversation
Choose:
- chance
- coincidence
- accident
- unexpected event
- chance meeting
- chance encounter
These words are natural and easy to understand.
For Positive Situations
Choose:
- serendipity
- stroke of luck
- piece of luck
- fortunate accident

These alternatives work when the unexpected event produces a positive result.
For Formal Writing
Choose:
- happenstance
- fortuity
- concurrence
- convergence
- confluence
- unexpected occurrence
These words can make formal or analytical writing more precise.
For Storytelling
Choose:
- twist of fate
- quirk of fate
- chance encounter
- chance meeting
- happenstance
These expressions can make a narrative more descriptive.
When Emphasizing Randomness
Choose:
- chance
- random event
- random occurrence
- chance event
- accidental occurrence
These are useful when the main idea is that something was not planned.
When Emphasizing Meaningful Connection
Choose:
- synchronicity
- convergence
- confluence
These terms suggest that separate events or circumstances came together in a noticeable or meaningful way.
Common Mistakes When Using Coincidence Synonyms
Mistake 1: Treating Every Synonym as Exactly Equal
Not every alternative has the same meaning.
For example, serendipity normally suggests something fortunate, while coincidence can describe either a positive or negative situation.
Mistake 2: Using “Fluke” for Every Coincidence
A fluke generally describes an unusual result or success.
It is not always a natural replacement for coincidence.
Less natural:
“Meeting my sister at the airport was a fluke.”
More natural:
“Meeting my sister at the airport was a coincidence.”
Mistake 3: Using “Synchronicity” in Ordinary Situations
Although synchronicity can describe striking coincidences, it carries a more specialized or reflective meaning.
For simple everyday situations, coincidence or chance is usually clearer.
Mistake 4: Assuming a Coincidence Means Causation
Two events happening together does not automatically mean that one caused the other.
For example, two people buying the same book on the same day may be a coincidence. That fact alone does not establish a causal relationship.
Mistake 5: Using “Accident” When You Mean “Chance”
An accident can imply that something happened unintentionally, and it is often associated with mistakes or harmful events.
Chance is usually better when you simply mean something happened randomly.
Examples of Coincidence Synonyms in Sentences
Here are several examples showing how the alternatives change the tone:
- Coincidence: “It was a strange coincidence that we met again.”
- Chance: “We met again by chance.”
- Happenstance: “Our friendship began through happenstance.”
- Serendipity: “Discovering the opportunity was pure serendipity.”
- Fluke: “His unexpected victory was a fluke.”
- Fortuity: “By fortuity, she arrived at exactly the right moment.”
- Synchronicity: “She saw their meeting as synchronicity.”
- Convergence: “Their paths crossed through a convergence of circumstances.”
- Stroke of luck: “Finding an open hotel room was a stroke of luck.”
- Twist of fate: “A twist of fate brought them together years later.”
