The aim of the paper is to estimate the technical efficiency of insurance providers in the Visegrad Group countries in the period 2009–2016 using data envelopment analysis (DEA). The insurance sector in these countries underwent significant changes in the analysed period. during the last two decades. According to the results of the analysis, the average efficiency of insurance companies was approximately 65–80% in the period under study. There were, however, considerable differences among individual insurance companies as well as among the national insurance sectors. The most efficient insurance sectors were those of Hungary and Poland, and the least efficient that of Slovakia. The overall development of efficiency was almost stable, and efficiency decreased in 2012 and 2014. The reason for the inefficiency fall was the decrease in number of premiums written and net income and the high level of costs.
