130 Informative Essay Topics

Many types of essays can be assigned to students depending on their course of study and level of education. From argumentative to narrative, each essay will require unique formatting and writing styles to ensure that a student meets the standards of their instructor.

However, the most common type of essay assigned to students from high school to college is the informative essay. The purpose of this type of essay is to inform readers about a particular topic such as:

  • an object
  • a person
  • an event
  • a phenomenon
  • a place

Unlike other essay styles, the informative essay is meant to be entirely informational, free from personal opinions and persuasive arguments. This means that more research and information gathering will be required in order to write an informative essay effectively.

Writing an informative essay isn’t without its challenges, but the most difficult for students assigned with the task is coming up with a topic for the essay.

A topic that is too broad may overwhelm the research process. On the other hand, a subject too specific may not yield enough credible sources.

Furthermore, the challenge of choosing the right topic for an informative essay is also compounded by the strict word limit usually set for this type of essay.

Fortunately, this list of 130 informative essay topics will inspire students to start writing an informative and engaging essay in no time!

And along with the handy guide on how to write an informative essay, students can rest assured that they are well on their way to writing an informative essay that will earn them a passing grade.

Essential Factors to Writing an Informative Essay

Before getting into informative essay structure and topics, it is necessary to understand the essential factors of creating an informative essay.

The first thing to understand is that an informative essay should answer the five W’s:

  • Who
  • What
  • Where
  • When
  • Why

Informative essays can also answer the question, ‘how.’ If you are not answering these questions with statements, statistics, and facts, you may be writing a different kind of essay that won’t earn you the grade you want.

To keep yourself on track when writing an informative essay, be sure to choose a topic that serves one of the following functions:

  • Analyzes data
  • Compares and contrasts
  • Defines a term
  • Provides a how-to

By choosing one of the functions mentioned above, you can ensure that you write an informative essay free from personal opinion or subjective thought.

How to Write an Informative Essay

When writing an informative essay, it is helpful to create an outline for each section. After completing (or while performing) research, organize your essay outline into three sections.


The introduction of an informative essay should start with an interesting ‘hook’ statement. This statement is designed to get the reader excited about the writing by posing an interesting question, stating a bold fact, or describing an interesting scene.

After the hook has been written, you might consider adding in a few bits of background information that explores ideas related to your main topic.

The final sentence of the introduction should be a thesis that includes a statement of purpose and a focus. The thesis should show the reader what question will be answered in the body paragraphs and give them a general idea of what to expect from the rest of the essay.

Body Paragraphs

The body of your informative essay should be no less than three paragraphs. It should contain the bulk of your research with facts presented in order of least to most critical or need-to-know.

Each paragraph should start with a strong topic sentence that leads into each fact. The remaining sentences should flow together to support your thesis. The section should end with a final sentence wrapping up your point and transitioning to the next paragraph.

Remember that informative essays should only include provable facts, statistics, and statements, so be sure to avoid anything that sounds judgemental, subjective, or too much like a personal opinion.

For example, if your essay is about the benefits of mentoring young adults, you should avoid writing,

“Mentoring would benefit people because it allows them to have someone looking out for their best interests.”

And instead, try writing something more like,

“Research shows that 75% of participants in a mentorship program felt more comfortable about entering the workforce after becoming involved in the program.”


The conclusion of an informative essay should reiterate your thesis and end with a final statement that solidifies the essay’s purpose.

The final statement could be in the form of a rhetorical question that encourages the reader to go out and learn more, an action statement that urges the reader to take some form of action, or a call-to-action statement asking the reader to do something.

In an informative essay, the most crucial element of the conclusion isn’t the writing itself, but that it ends on a high note for the reader.
