Turbo Assembler (sometimes shortened to the name of the executable, TASM) is an assembler for software development published by Borland in 1989. It runs on and produces code for 16- or 32-bit x86 MS-DOS and compatibles or Microsoft Windows. It can be used with Borland's other language products: Turbo Pascal, Turbo Basic, Turbo C, and Turbo C++. The Turbo Assembler package is bundled with Turbo Linker and is interoperable with Turbo Debugger.

Borland advertised Turbo Assembler as being 2-3 times faster than its primary competitor, Microsoft Macro Assembler (MASM). TASM can assemble source in a MASM-compatible mode or an ideal mode with a few enhancements. Object-Oriented programming was added in version 3. The last version of Turbo Assembler is 5.4, with files dated 1996 and patches up to 2010; it is still included with Delphi and C++Builder.
TASM itself is a 16-bit program. It will run on 16- and 32-bit versions of Windows, and produce code for the same versions, but it does not generate 64-bit x86 code. Turbo Assembler 5.0 (at least) also contains a 32-bit PE version of tasm called TASM32.EXE.
Example edit
A Turbo Assembler program that prints 'Merry Christmas!':
.model small
.stack 100h
.data
msg db "Merry christmas!",'$'
.code
main proc
mov ax, SEG msg
mov ds, ax
mov dx, offset msg
mov ah, 9
int 21h
mov ax, 4c00h
int 21h
main endp
end main
