Public Health Wales has described TB as a "serious public health concern" requiring action to prevent further increases.
Despite the rise, Wales continues to have the lowest TB rate in the UK.
The UK-wide average stands at 7.8 cases per 100,000 people, significantly higher than Wales' rate of 3.0.
Health officials emphasise that early diagnosis and prompt treatment are crucial to limiting the impact on patients.
Timely intervention also helps prevent the spread of infection in the wider community.
Professor Meng Khaw, PHW's national director of health protection and screening, said TB remains a significant health challenge.
He explained: "The increase in TB cases in Wales highlights the urgent need for strengthened prevention strategies and improved access to early diagnosis."
Public Health Wales is working to address these concerns through increased awareness campaigns, recognising that early identification of cases is essential to controlling the spread of this infectious disease.

The World Health Organisation has called TB the "world's deadliest infectious disease".
The rising cases underscore the importance of public awareness about TB symptoms, with anyone experiencing persistent cough, fatigue, or breathing difficulties urged to seek medical advice.
"[The condition] is an infection that usually affects the lungs," notes the NHS.
"It can be treated with antibiotics but can be serious if not treated. There's a vaccine that helps some people who are at risk from tuberculosis."
