基本組合編程語言（），是一種電腦程式設計語言，源自更早的CPL語言，1967年由劍橋大學的馬丁·理察德所發展出來的
。
概述
Richards試著移除了CPL中最複雜的組成，第一支BCPL compiler在IBM 7094電腦中完成。身為早期程式語言的BCPL，如今已不再廣泛使用，但它的影響卻是深遠的，今日流行的C語言即是參考BCPL所設計。BCPL被认定为第一个，作为BCPL后代语言，C语言使用花括号来表示块结构。
範例
下列是馬丁查理斯的BCPL发行中的范例。
打印阶乘：
GET "LIBHDR"
LET START() = VALOF $(
FOR I = 1 TO 5 DO
WRITEF("%N! = %I4*N", I, FACT(I))
RESULTIS 0
$)
AND FACT(N) = N = 0 -> 1, N * FACT(N - 1)
N皇后問題：
GET "LIBHDR"
GLOBAL $(
COUNT: 200
ALL: 201
$)
LET TRY(LD, ROW, RD) BE
TEST ROW = ALL THEN
COUNT := COUNT + 1
ELSE $(
LET POSS = ALL & ~(LD | ROW | RD)
UNTIL POSS = 0 DO $(
LET P = POSS & -POSS
POSS := POSS - P
TRY(LD + P > 1)
$)
$)
LET START() = VALOF $(
ALL := 1
FOR I = 1 TO 12 DO $(
COUNT := 0
TRY(0, 0, 0)
WRITEF("%I2-QUEENS PROBLEM HAS %I5 SOLUTIONS*N", I, COUNT)
ALL := 2 * ALL + 1
$)
RESULTIS 0
$)
