The Spanish Indoor Athletics Championships (Spanish: Campeonato de España de Atletismo en pista cubierta) is an annual indoor track and field competition organised by the Royal Spanish Athletics Federation (RFEA), which serves as the Spanish national championship for the sport.^[1] Typically held over two days in February during the Spanish winter, it was first added to the national calendar in 1965, supplementing the main outdoor Spanish Athletics Championships held in the summer since 1917.^[2] It celebrated its 50th edition in 2014.^[3]

The following athletics events feature as standard on the Spanish Indoor Championships programme:

• Sprint: 60 m, 200 m, 400 m
• Distance track events: 800 m, 1500 m, 3000 m
• Hurdles: 60 m hurdles
• Jumps: long jump, triple jump, high jump, pole vault
• Throws: shot put
• Combined events: heptathlon (men), pentathlon (women)

At the first three editions, non-standard distances of 600 metres, 1000 metres and 2000 metres were contested. A 5000 m race walk for men was introduced in 1979, while a women's 3000 m walk was contested from 1984. Racewalking events ceased to be part of the national championships after 1994. The men's combined event was an octathlon in 1981, 1982, 1987, 1988 and 1989. Women competed in a sextathlon instead of a pentathlon from 1981 through 1986.^[1]
