ThePhocaea family (/foʊˈsiːə/foh-SEE-ə; adj.Phocaean;FIN:701) is a collisionalfamily ofasteroids located between 2.25 and 2.5 AU in the inner region of theasteroid belt. Phocaea asteroids are of stonyS-type composition and have orbits witheccentricities greater than 0.1 andinclinations between 18 and 32°.^[1] The family has an estimated age of 2.2 billion years and derives its name from its most massive member,25 Phocaea which is about 75 km in diameter. Several Phocaean asteroids are alsoMars-crossers.^[2][3]: 23

The Phocaea family region contains other collisional families such as the recently identifiedcarbonaceous,Tamara family,^[4] named after its potentially largest member326 Tamara. The family has an estimated age of 264 million years. Several clumps around290 Bruna (Bruna family),1192 Prisma and6246 Komurotoru, as well as(17628) 1996 FB₅,(19536) 1999 JM₄ and(26142) 1994 PL1 have also been detected.^{[2]: 1514, 1515}
