Ang '''Beta Ceti''' (β Cet, β Ceti) ay ang pinakamaliwanag na [[bituin]] sa [[konstelasyon]] ng [[Cetus]]. Kahit na mayroon itong [[pagtatanda ni Bayer]] na "beta", ito ang talagang mas maliwanag kaysa sa [[Alpha Ceti]]. May tradisyunal na pangalan itong'''Deneb Kaitos''' at '''Diphda'''. Madaling makita ang naranghang higanteng ito dahil sa lokasyon nito sa madilim na seksyon ng [[panlangit na timbulog]]. Base sa sukatang [[paralaks]], makikita ito sa tinantiyang layo na {{Convert|96.3|ly|pc|abbr=off|lk=on}} mula sa Mundo.<ref name=aaa474_2_653/>
