Weekly and monthly samples were collected in the Barra de Navidad coastal lagoon (Jalisco, Mexico) from February 2011 to August 2016 to assess the reproductive biology of this species. Observed total sex ratio (F1.00:M1.03) was not significantly different from the expected 1:1 ratio. Females were, on average, larger than males. The observed monthly gonadosomatic index, percentage of mature gonads, mean oocyte diameter, and ovarian-wall thickness suggest that the species reproduces year-round, with an important reproductive season lasting from April to August. Females were classified as partial spawners with asynchronous oocyte development, and males showed unrestricted spermatogonial testes. The presence of spawned individuals and hydrated oocytes in certain months indicates that the species could be spawning in the lagoon; however, the occurrence of eggs and larvae needs to be demonstrated to ascertain this statement. This was the first time length at sexual maturity was assessed for female (10.84 cm) and male (10.23 cm) A. mazatlanus. Achirus mazatlanus es uno de los peces planos más abundantes de la costa mexicana del Pacífico, pero la mayoría de sus aspectos biológicos y reproductivos se desconocen. Se realizaron muestreos semanales y mensuales en la laguna costera de Barra de Navidad (Jalisco, México) de febrero de 2011 a agosto de 2016 con el fin de conocer la biología reproductiva de esta especie. La proporción sexual (H:M) total (1.00:1.03) no difirió de la relación esperada de 1:1. Las hembras fueron, en promedio, más grandes que los machos. Los resultados observados para el índice gonadosomático mensual, el porcentaje de gónadas maduras, el diámetro medio de los ovocitos y el grosor de la pared ovárica sugieren que la especie se reproduce durante todo el año, con una estación reproductiva importante de abril a agosto. Las hembras fueron clasificadas como desovadoras parciales con desarrollo asincrónico de los ovocitos. Los machos presentaron testículos con desarrollo espermatogonial sin restricción. Debido a que se observaron individuos maduros y ovocitos hidratados durante ciertos meses, la especie puede estar desovando dentro de la laguna; sin embargo, sería necesario demostrar la presencia de huevos y larvas para asegurar esto. Por primera vez, se calculó la longitud de madurez sexual para las hembras (10.84 cm) y los machos (10.23 cm) de A. mazatlanus.
