Entrepreneurial alertness refers to recognizing opportunities in the environment without actively seeking them. Recognizing opportunities is linked to human awareness, skills, and knowledge. A person with highly developed entrepreneurial alertness will identify business opportunities that others cannot see. Recognizing opportunities is crucial for undertaking entrepreneurial ventures and assessing their success. However, it's not only important to recognize opportunities but also threats that can negatively impact a business's operations. Developed entrepreneurial alertness can be observed through creativity and innovation, as creative people can connect seemingly unrelated information and thus create new innovations. Innovation ensures competitiveness in the market, which every business strives for. The degree of entrepreneurial alertness can be examined through scanning and searching for information from the environment, associating and connecting information even when it seems unrelated, and evaluating and judging profitable versus unprofitable opportunities. This paper presents a study that analyzes the development of entrepreneurial alertness among young people under the age of 25 in the Republic of Croatia. The results indicate a high level of entrepreneurial awareness among the respondents, but a significant portion of young people have not yet utilized their entrepreneurial potential due to the obstacles they face. Most respondents demonstrated a welldeveloped sense of entrepreneurial alertness, but a notable number showed a low level of entrepreneurial alertness. Despite the prevailing majority, the entrepreneurial alertness of the respondents is still not fully developed, indicating a need for its improvement in the future.
