Multiplan是微软公司（Microsoft）于1982年推出的电子试算表软件，在CP/M系统上大获成功，并试着移植到MS-DOS 和 Xenix。但在MS-DOS系统上，Multiplan败给了Lotus 1-2-3。之后微软推出Excel才逆转整个局面。

Multiplan was an early spreadsheet program developed by Microsoft. Known initially by the code name "EP" (for "Electronic Paper"), it was introduced in 1982 as a competitor for VisiCalc.

Multiplan was released first for computers running CP/M; it was developed using a Microsoft proprietary p-code C compiler as part of a portability strategy that facilitated ports to systems such as MS-DOS, Xenix, Commodore 64 and 128, Texas Instruments TI-99/4A, Radio Shack TRS-80 Model II, TRS-80 Model 4, TRS-80 Model 100 (on ROM), Apple II, and Burroughs B-20 series.
