The <i>PEBP</i> gene family is involved in many biological processes in plants, including plant growth and development, flowering regulation, light response, and abiotic stress response. But there is little information about the role of the <i>PEBP</i> gene family in <i>Cymbidium</i> species. In this study, we identified 11, 9, and 7 <i>PEBP</i> genes in <i>C. ensifolium</i>, <i>C. sinense</i>, and <i>C. goeringii</i>, respectively, and mapped them to the chromosomes. We also studied the physicochemical characteristics of the proteins encoded by these <i>PEBP</i>s and analyzed their intra-species collinearity, gene structure, conserved motifs, and cis-acting elements. Furthermore, a total of forty PEBP genes from <i>C. sinense</i>, <i>C. ensifolium</i>, <i>C. goeringii</i>, <i>Phalaenopsis</i>, and <i>Arabidopsis</i> were divided into three clades based on the phylogenetic tree. The expression patterns of 11 <i>PEBP</i> genes in different tissues and organs of <i>C. ensifolium</i> were analyzed based on transcriptome data, indicating that the <i>CePEBP</i>s might play an important role in the growth and development, especially in the flower bud organs (1–5 mm). <i>CePEBP5</i> plays an indispensable role in both the vegetative and reproductive growth cycles of <i>C. ensifolium</i>. <i>CePEBP1</i> is essential for root development, while <i>CePEBP1</i>, <i>CePEBP3</i>, <i>CePEBP5</i>, and <i>CePEBP10</i> regulate the growth and development of different floral organ tissues at various stages. The findings of this study can do a great deal to understand the roles of the <i>PEBP</i> gene family in <i>Cymbidium</i>.
