100+ Dissertation Topic Ideas for Students in 2026

If you are still deciding what to write your dissertation on, you are probably not short of ideas. The problem is choosing one that actually works for your subject.

You might find a topic interesting, but then struggle to find enough studies on it. Or you may have plenty of research available but feel no connection to the subject.

We have put together more than 100 dissertation topic ideas covering different subjects studied at UK universities. There are options for students in law, nursing, education, accounting, public health and other fields.

Hopefully, you will find something here that gives you a place to start.

How to Choose the Right Dissertation Topic?

Before settling on a topic, make sure it is relevant to your degree and manageable within your deadline. 

Consider these five points:

  1. Course relevance: Does the topic match your degree and university requirements?
  2. Research gap: Is there an issue that needs further investigation?
  3. Available information: Can you find enough journal articles, reports or useful data?
  4. Time and resources: Can you complete the research before your deadline?
  5. Ethical approval: Will your research involve patients, children or other participants who require ethical approval?

Once you choose a suitable topic, dissertation proposal writing helps you plan your research and explain how you intend to carry it out. 

For example, instead of researching social media and mental health broadly, you could explore how Instagram use affects body image among UK university students aged 18–24.

A focused topic is easier to research, organise and complete.
